ACS - American Chemical Society Practice Test

โ–ถ

Choosing where to submit your chemistry manuscript is rarely a clean decision. You weigh scope. You weigh prestige. And โ€” almost always โ€” you check the impact factor before you do anything else. The American Chemical Society publishes more than 80 peer-reviewed journals, and their impact factors swing from under 2 to over 60 depending on the title and the year.

This page is a working directory. We'll lay out the most recent JCR cycle data for the journals chemists actually submit to, then walk through what those numbers really mean โ€” and where they fall apart. If you've ever stared at a list of ACS journal impact factors wondering which one matches your work, you're in the right place.

Quick reminder before we dig in. Impact factor is calculated by Clarivate's Journal Citation Reports (JCR), released each summer for the prior two publication years. The 2024 JCR cycle (published mid-2024) covers citations to articles from 2022 and 2023 โ€” that's the data you'll see referenced across this guide. Newer journals (those founded after roughly 2020) sometimes don't yet have a stable impact factor, since they need two full publication years of indexed content before Clarivate calculates a value.

Why does this matter beyond bragging rights? Three reasons. Career evaluators still glance at these numbers when they're flipping through your CV. Funding agencies in many countries still tie tier-1 publications to grant scoring rubrics. And โ€” most practically โ€” the impact factor tells you something real about how often the average paper in that venue ends up cited, which is a rough proxy for how visible your own work will be once it's published there.

One thing we'll keep repeating throughout this guide: impact factor is a coarse signal, not a precision tool. Use it the way you'd use a thermometer in cooking โ€” directionally useful, not the only thing that matters.

Let's start where most chemists do: the headline numbers. ACS's flagship titles compete with Nature-family journals, while their broad-scope titles like ACS Omega are pitched as fast, open-access alternatives to bigger names. The impact factors below tell you, at a glance, how often the average paper in each journal got cited in the JCR cycle that closed in 2024.

Don't read the table as a ranking. Read it as a snapshot. A 9.0 impact factor in a materials journal isn't comparable to a 9.0 in a biochemistry journal โ€” citation cultures vary wildly across subfields. Chemistry, generally, sits in the middle: higher than pure math, lower than clinical medicine. So a strong ACS specialty journal hitting 10+ is genuinely strong work, even though that number would look modest in a clinical research category.

A few other numbers worth memorizing if you work in chemistry. Inorganic Chemistry sits around 4. Organometallics sits around 4. Journal of Organic Chemistry sits around 3.5. Analytical Chemistry sits around 7. These aren't headline numbers, but they're respected Q1 journals in their subject categories โ€” and a paper in any of them tells reviewers that you write tightly-scoped, technically clean chemistry.

The newer entries in the ACS catalog deserve attention too. JACS Au (the open-access companion to JACS) launched in 2021 and is climbing fast. ACS Catalysis Au, ACS Materials Au, and a handful of other "Au" titles followed. Their impact factors are still settling, but the editorial standards mirror their parent journals โ€” useful homes when you need open access without leaving the ACS ecosystem.

What Impact Factor Actually Measures

Impact factor is a simple ratio: citations in year N to papers published in years N-1 and N-2, divided by the count of citable items in those two years. That's it. It does not measure paper quality, author quality, or peer review rigor โ€” only how often the average paper in a journal gets cited within a narrow two-year window. A high-IF journal can publish papers that nobody cites; a low-IF journal can publish papers that change a field. Treat the number as a coarse signal, never a verdict.

Some authors fixate on the absolute number. Bad habit. What matters more is where a journal sits inside its category. Clarivate ranks every journal in JCR by quartile โ€” Q1 means top 25% of its subject category, Q4 means bottom 25%. A Q1 journal with an impact factor of 6 often signals higher selectivity than a Q2 journal sitting at 9 in a more citation-heavy field. Quartiles normalize across subject categories in a way that absolute impact factors never do.

The other dimension worth tracking: trajectory. ACS Energy Letters launched in 2016 and climbed past 22 within seven years. That kind of climb tells you the editorial team is curating tightly and the field itself is exploding. Compare that to long-established titles like Inorganic Chemistry, which sits around 4 โ€” respected, broad, stable, but not a meteor. Both are useful. They just signal different things on a CV.

A practical move: pull up the journal's five-year impact factor alongside its two-year number. Clarivate publishes both. If the five-year is meaningfully higher than the two-year, the journal's citation half-life is long โ€” typical for methods-heavy or theory-heavy work. If the two-year is higher, citations spike fast and fade fast, which is common in hot application areas. Either pattern is fine. Knowing which one you're looking at saves you from misreading a single year's snapshot.

Major ACS Journals by Submission Tier

๐Ÿ”ด Chemical Reviews (~62)

Mostly invited, comprehensive review articles. Highest impact factor in the ACS portfolio. Best fit: senior PIs writing definitive field overviews. Average review length: 50โ€“150 pages.

๐ŸŸ  ACS Energy Letters (~22)

Fast-turnaround letters in energy science. Climbed sharply since 2016 launch. Best fit: high-impact, short-format energy results with clear quantitative advances.

๐ŸŸก ACS Nano (~18)

Nanoscience flagship. Wants mechanism, measurement, and application in one paper. Best fit: nanomaterials papers with quantitative novelty plus device or biological context.

๐ŸŸข ACS Central Science (~18)

Open-access flagship spanning all chemistry. High visibility, broad audience. Best fit: discoveries that cross chemistry sub-disciplines or have unusual interdisciplinary appeal.

๐Ÿ”ต JACS (~16)

Journal of the American Chemical Society. Flagship general chemistry. Best fit: fundamental advances in any chemistry sub-area with clean, complete data and clear novelty.

๐ŸŸฃ ACS Catalysis (~13)

Catalysis-specialist title. Best fit: heterogeneous, homogeneous, or biocatalysis papers with strong mechanistic insight or industrial relevance.

So how do you actually use these numbers? Three honest applications, in order of usefulness.

First, calibrate scope. If your finding feels like a JACS-tier mechanism story but you're shopping it to ACS Omega because "the impact factor's fine," you're probably underselling. Reverse is also true โ€” a methods paper aimed at a 60+ impact factor review journal is a long shot, and you'll waste months in desk-rejection cycles. Scope match beats impact factor chase every single time.

Second, gauge competition. Higher impact factor usually correlates with higher rejection rates. ACS Nano rejects somewhere north of 70% of submissions. Chemical Reviews is invitation-driven for most issues. Knowing that upfront saves you the sting of a fast desk-reject email at 11 PM. Build a realistic submission plan โ€” first-choice journal, two backups in descending order of selectivity, and a clear "we'll just publish it" venue at the bottom of the list.

Third, signal to evaluators. Like it or not, hiring committees, grant panels, and tenure reviewers still glance at the impact factor of where you publish. That's changing โ€” slowly โ€” but it's still the reality in 2025 and 2026. The signal is strongest in your first three to five publications as an independent investigator, and fades as your full record speaks for itself.

A fourth, more subtle application: impact factor is a coarse signal of reach. A paper in a 20+ IF journal reaches a broader audience by default than the same paper in a 4-IF journal. That matters if your work has implications beyond your immediate subfield. It matters less if you're publishing for a tightly-defined community that reads two or three specialty journals anyway.

๐Ÿ“‹ Top-Tier Discovery

You have a result that meaningfully changes how a field thinks about a problem. Mechanism-level evidence. Multiple complementary techniques. A clear story.

  • JACS (~16) โ€” broad chemistry, fundamental advances
  • ACS Nano (~18) โ€” nanomaterials with mechanism + application
  • ACS Central Science (~18) โ€” cross-disciplinary or unusually broad appeal
  • ACS Catalysis (~13) โ€” catalysis-specific mechanism stories

Reasonable rejection rates here run 60โ€“80%. Plan for a Q2 backup journal before you submit.

๐Ÿ“‹ Strong Specialty Result

Solid, complete work in a clear sub-area. Not field-changing, but well-executed and useful. This is the bulk of good chemistry publishing.

  • ACS Applied Materials & Interfaces (~9) โ€” materials with applications
  • ACS Sensors (~9) โ€” chemical/biological sensing
  • ACS Synthetic Biology (~4.7) โ€” synbio applications
  • ACS Chemical Biology (~4) โ€” chem-bio mechanism work
  • ACS Infectious Diseases โ€” antimicrobial chemistry

Acceptance rates run 30โ€“50%. Faster turnaround than top-tier titles.

๐Ÿ“‹ Fast-Track Open Access

You need a quick, peer-reviewed, open-access home for solid work. APCs typically apply unless you're covered by an institutional agreement.

  • ACS Omega (~4) โ€” broad-scope OA megajournal
  • ACS Central Science (~18) โ€” selective OA, broad scope
  • ACS Au journals โ€” sub-discipline OA companions (e.g., JACS Au, ACS Catalysis Au)

Decision times often 30โ€“60 days. Reproducibility and completeness matter more than novelty.

๐Ÿ“‹ Polymer or Electronic Materials

Materials work with a specific focus โ€” electronics, polymers, energy materials, or composites.

  • ACS Applied Polymer Materials โ€” polymer applications
  • ACS Applied Electronic Materials โ€” electronic materials
  • ACS Applied Energy Materials โ€” batteries, fuel cells, photovoltaics
  • Chemistry of Materials (~9) โ€” synthesis-focused materials chemistry

Specialty applied journals โ€” strong choice when scope is a tight fit, even if impact factor looks modest.

Now for the cracks in the system. Impact factor has real, well-documented problems, and any researcher using it as a sole metric is going to get burned eventually.

The math is skewed. A single highly-cited paper can drag a journal's impact factor up 30%. Editors know this, and you'll occasionally see a low-volume title publish a deliberately citation-baiting review article to juice next year's number. The metric is also a two-year window โ€” which punishes fields where papers mature slowly (think synthetic methodology, where citations build over five to ten years) and rewards fast-moving fields like nanotech.

Self-citation matters too. Some journals encourage authors to cite recent papers from the same journal during revision. Clarivate suppresses journals caught doing this aggressively, but mild patterns still inflate numbers. And โ€” this one bites grad students โ€” impact factor measures the journal, not your paper. Your individual paper might never be cited even if it lands in a 20+ IF venue.

There's a deeper problem too: the numerator and denominator don't always count the same things. Clarivate counts citations to everything in the numerator (including editorials, news pieces, and front matter), but only counts "citable items" (original research articles and reviews) in the denominator. Journals that publish a lot of high-citation front matter can mathematically inflate their impact factor without any change in the quality of their original research. ACS journals are generally clean here, but it's worth knowing the trick exists.

Practice ACS exam questions

If impact factor isn't enough, what should you look at? Several complementary metrics give a fuller picture, and most are free to check on the journal's homepage or via Scopus/Web of Science.

CiteScore from Scopus uses a four-year window and a broader citation pool. Numbers run slightly higher than impact factor for the same journal, but trends usually agree directionally. SJR (SCImago Journal Rank) weights citations by the prestige of the citing journal โ€” a citation from a top-tier title counts more than one from a low-tier title.

SNIP (Source Normalized Impact per Paper) normalizes for citation potential across subject fields. And h5-index from Google Scholar measures the largest number h such that h articles from the journal in the last 5 years each have at least h citations โ€” a robust, manipulation-resistant alternative.

For chemistry specifically, looking at all four alongside impact factor gives you the cleanest read. If a journal scores well across the board, the headline number is probably reliable. If impact factor is the outlier, dig deeper.

Check JCR quartile (Q1/Q2/Q3/Q4) within the specific subject category, not just absolute impact factor
Read 3โ€“5 recent papers in the journal and compare their depth/scope to your manuscript
Confirm scope match โ€” read the journal's aims and scope statement, not just the title
Check average time from submission to decision (most journals publish this on their homepage)
Verify open access fees and institutional agreements through ACS Read & Publish
Look at the editorial board โ€” do you know names in your sub-area? That's a signal
Check CiteScore (Scopus) and SJR alongside impact factor for a fuller picture
Confirm there's no obvious overlap with a paper your group recently published there

Here's the practical answer to "which ACS journal should I aim for?" โ€” it depends almost entirely on what you've done. The structure cards below break the major journals into the kinds of papers they actually want, beyond just the topical scope listed on the masthead.

Pay attention to the "best fit" line in each card. Editors tell you in their cover letters what they're looking for, and the patterns are remarkably consistent year over year. ACS Nano wants a mechanism, a measurement, and an application โ€” all three. JACS wants the cleanest version of a fundamental advance. ACS Omega wants solid, complete, reproducible work without the novelty bar.

Beyond these flagships, the ACS portfolio includes a long tail of specialty journals where strong work goes to find its natural audience. ACS Infectious Diseases (around 4.5) is a respected home for antimicrobial and chemical biology work. ACS Synthetic Biology (around 4.7) hosts metabolic engineering and synthetic biology. ACS Chemical Biology (around 4) covers chemical probes and mechanism work. These look modest next to the headliners, but their citation pace tells you these are dense, technical, well-read journals in tight communities.

Pros

  • Easy, widely-recognized shorthand for journal selectivity
  • Reasonable correlation with desk-rejection rates
  • Useful for shortlisting target journals from a long list
  • Still weighted in hiring/grant decisions in most countries
  • Updated annually with reasonable transparency from Clarivate

Cons

  • Two-year window penalizes slow-citing fields like synthetic methodology
  • One viral paper can spike a journal's impact factor by 20%+
  • Measures the journal, not your individual paper
  • Citation cultures vary wildly across chemistry subfields
  • Encourages chasing prestige over scope match
  • Self-citation patterns can inflate numbers without Clarivate suppression

One thing worth flagging before you submit anywhere โ€” open access status affects citation rates. Gold open access journals like ACS Omega, ACS Central Science, and (since 2023) several others under ACS's transformative agreements tend to accumulate citations faster than paywalled journals, especially in international collaborations. That's part of why ACS Central Science punches above its weight on impact factor.

The flip side: APCs (article processing charges) for ACS gold OA journals range from roughly $2,500 to $5,000. Check whether your institution has a Read & Publish agreement with ACS โ€” many R1 universities and major European institutions do, which can zero out the fee for corresponding authors. Some funding agencies (NIH, Wellcome, UKRI, ERC) explicitly cover OA fees as a grant line item. If yours does, factor that into your submission strategy from the start.

Hybrid open access (paid OA option in a subscription journal) is a different animal. It costs about the same as gold OA but doesn't always boost citation rates as much, because the journal's default state in indexers is still "subscription." If you're paying for OA, gold OA journals typically give you better value per citation.

Take the ACS practice test

Let's get tactical. The tabs below split the ACS portfolio into four common submission scenarios. Pick the tab that matches your situation, then look at the journals listed inside.

Then a final exam-style sanity check before you actually hit submit. Read the abstract of the three most recently accepted papers in your target journal. Are they meaningfully more impressive than yours? If so, aim lower. Meaningfully less impressive? Aim higher โ€” or at the same tier with a stronger cover letter. About the same? You're in the right range.

One last honest observation that doesn't fit neatly anywhere else. The impact factor system isn't going away, but it's slowly losing dominance. Funders like the Wellcome Trust and major European agencies have signed DORA (the San Francisco Declaration on Research Assessment), which formally rejects using journal impact factor in hiring and grant decisions.

Some U.S. institutions are following. Slowly. What's replacing it isn't a single metric โ€” it's a portfolio view: a few selected papers, narrative descriptions of impact, code and data availability, preprint deposits, and qualitative peer assessment. None of which fits in a single number, which is exactly the point.

Practically, this means early-career chemists should think about both systems. The legacy impact-factor system still dominates in many countries and many U.S. private institutions. The narrative-portfolio system is more common at progressive European universities and a growing number of U.S. R1s.

If you're targeting positions in both worlds, you need a CV that reads well in either framework โ€” a small number of high-impact-factor publications anchoring the legacy view, plus a clear narrative thread connecting your body of work for the portfolio view. ChemRxiv preprints help bridge the two: they signal openness while still letting you anchor your portfolio with a strong journal placement.

Bookmarks worth keeping. The ACS Publications "Latest Articles" page updates daily, and most ACS journals now publish ASAP (As Soon As Publishable) versions weeks ahead of issue assignment. If you're tracking a competitive area, set up keyword alerts in ACS's portal or via Scopus โ€” you'll see new methods landing weeks before your competitors notice.

Practice navigating these tools the same way you'd practice exam questions. There's real value in knowing where to look quickly, especially when a reviewer asks you to address a paper that landed two weeks ago. Run through a few ACS practice questions to keep the fundamentals sharp while you're between manuscript drafts.

The bottom line is unromantic but true. Pick a journal whose readers will care about your finding. Match your scope honestly. Use impact factor as one signal, not the deciding vote. Track CiteScore, SJR, and quartile alongside it. And remember that your most-cited paper is rarely your highest-impact-factor one โ€” research careers are built on a portfolio of work, not on a single trophy publication. Good luck with the submission.

ACS Questions and Answers

What's the highest impact factor among ACS journals?

Chemical Reviews holds the highest impact factor in the ACS portfolio, sitting around 62 in the 2024 JCR cycle. It's a review-only journal, mostly invited, focusing on comprehensive overviews of chemistry subfields. The high impact factor reflects the long-format, citation-heavy nature of comprehensive reviews โ€” not necessarily that it's the most selective ACS journal for original research.

Is ACS Nano higher impact factor than JACS?

Yes โ€” in the 2024 JCR cycle, ACS Nano (around 18) sits above JACS (around 16). That gap reflects the fast-growing nanoscience citation pool more than any quality difference. JACS publishes across all of chemistry; ACS Nano focuses on a narrower, citation-dense field. Both are top-tier ACS titles with rejection rates above 70%.

What is the impact factor of ACS Omega?

ACS Omega's impact factor sits around 4 in the most recent JCR cycle. It's the ACS open-access megajournal โ€” broad scope, solid peer review, faster decision times than the flagship titles. The lower impact factor reflects its volume and broad scope rather than weak quality. ACS Omega is a strong home for complete, reproducible work that doesn't need the novelty bar of JACS or ACS Nano.

How is the impact factor of ACS Applied Materials & Interfaces calculated?

Same as every other journal: Clarivate counts citations made in the JCR year (e.g., 2023) to articles published in the two prior years (2021 and 2022), then divides by the count of citable items published in those two years. ACS Applied Materials & Interfaces sits around 9 in the 2024 JCR cycle. The metric updates annually each summer.

Why did ACS Energy Letters climb so fast?

ACS Energy Letters launched in 2016 and hit an impact factor above 22 within seven years. Three reasons: tight editorial curation, a short-letter format that fits citation-dense energy research, and a field โ€” energy storage, photovoltaics, electrocatalysis โ€” that was exploding in publication volume. Fast-growing fields tend to produce fast-climbing impact factors because more papers cite recent work.

The editorial team has also been deliberate about scope, keeping volume relatively low and selectivity high.

Should I trust impact factor when choosing a journal?

Trust it as one signal among several, never as the deciding vote. Check the JCR quartile within the specific category, read recent papers in the journal, confirm scope match, and look at CiteScore and SJR alongside impact factor. A Q1 journal with a moderate impact factor often beats a higher-IF Q2 journal in a different subfield for career signaling and citation accumulation.

What's the impact factor of ACS Chemical Biology?

ACS Chemical Biology sits around 4 in the 2024 JCR cycle. It's a tightly-scoped chem-bio journal focusing on mechanism-of-action work, chemical probes, and chemical approaches to biological problems. The modest impact factor reflects the slower citation pace of mechanism-focused work, not weak quality โ€” and it's a respected Q1 journal in its subject category.

What's the difference between impact factor and CiteScore?

Impact factor is Clarivate's metric, using a 2-year citation window and the JCR-indexed citation pool. CiteScore is Scopus's competing metric, using a 4-year window and a broader citation pool. CiteScore numbers tend to run higher than impact factor for the same journal because of the longer window. Many researchers check both โ€” they often agree directionally but can disagree on absolute ranking, especially for newer journals.
