JACS Review Time

Associate Editors handle JACS manuscripts: the Editor assigns a manuscript to an Associate Editor, and the Associate Editor selects the reviewers. ACS says manuscripts that are ready to be reviewed when first submitted receive priority for initial processing and assignment, which is why a complete, easy-to-assess package moves faster.

JACS posts accepted papers online as Articles ASAP before they are assigned to an issue, and ACS records the publication date as whichever comes first. In practice that means the ASAP posting, not the printed issue, is the date other chemists will cite.

The JACS guidelines are unusually blunt about the first screen. Editors make an initial judgment about suitability for the journal's audience, and "a significant number of submissions are returned without sending them on for further processing." ACS does not attach a percentage to that sentence, and neither should you.

What the same page says JACS declines, in its own terms:

• Methodology Articles without one or more applications of widespread interest, which are declined with a recommendation for Manuscript Transfer to a specialized journal

• Papers that draw conclusions from existing data without significant new data and new predictions of broad interest

• Full Articles that mainly expand an earlier Communication with more data but no new conceptual insight

• Routine extensions of previously published related work

Two small rules also trip up otherwise strong submissions at intake: titles may not contain the words "First" or "Novel," and acronyms are not allowed in titles unless every kind of chemist would know them.

If JACS declines and suggests a transfer, take the suggestion seriously. Manuscript Transfer copies coauthors, suggested reviewers, files and submission answers into a new draft at the receiving ACS journal, which saves real days.

The Editors generally seek the advice of experts about manuscripts, and ACS publishes no reviewer count. The selection of reviewers is the prerogative of the Associate Editor handling the manuscript.

Reviewer identities are confidential. The guidelines are not consistent on reviewer suggestions: the cover-letter section says authors must suggest a minimum of six to eight persons competent to review the manuscript, while the peer-review section urges it and says suggestions are not a condition for submission (and another section calls them optional). Authors may also request that specific people not be used as reviewers, with reasons. Those suggestions are advisory. A short, well-chosen list still helps in a narrow subfield, where finding two willing experts is often the slowest step.

Reviewer comments at JACS tend to be technically detailed. Chemistry reviewers expect precise mechanistic arguments, complete characterization data, and statistical rigor for computational and quantitative studies.

The possible first-decision outcomes at JACS:

• Accept as is: Rare.

• Minor revision: Request for clarifications, additional data, or presentation improvements. ACS allots 14 days for minor revisions.

• Major revision: Substantial new experiments or analysis required. May go back to external reviewers. ACS allots 30 days for major revisions of Articles and 21 days for major revisions of Communications.

• Reject: No pathway to this journal in its current form. A declined paper can only come back as a revised version if the handling Associate Editor first consents, and the new cover letter must say that consent was given.

Reviewer unavailability. Chemistry is a large field and JACS covers it broadly. Highly specialized papers sometimes require reviewers in narrow subfields where available experts are few. Reviewer recruitment can take weeks before reviews even begin.

Related work you did not upload. JACS requires copies of any related work that is in press, accepted, submitted or in late preparation to go in as Supporting Information for Review Only at submission. Leaving it out invites a query before review can start.

Computational papers without chemical insight. For computational manuscripts, ACS requires that the level of theory and methodology be adequate for the problem at hand and that the manuscript provide significant chemical insights or have substantial predictive value. Papers that fall short of this are at risk at the initial editorial screen.

Revision complexity. Major revisions at JACS often require new synthesis, additional reaction scope experiments, or mechanistic studies. ACS allots 30 days for a major Article revision and 21 days for a major Communication revision; after that the revised manuscript is handled as a new submission with a new receipt date.

The status labels you see in the ACS submission system roughly map to these stages:

• Submitted: Received, being processed

• Under Editorial Review: An Associate Editor is doing the desk assessment

• Under Review: Out to external reviewers

• Decision Pending: Reviewers have returned comments, AE is making a decision

• Revision Requested: Decision has been made; you'll receive the letter

If your paper has been "Under Editorial Review" for more than 4 weeks, the desk assessment may have been escalated or the AE is consulting a board member. An inquiry after 4 weeks is appropriate.

If your paper has been "Under Review" for more than 8 weeks, reviewer tardiness is likely. An inquiry is reasonable.

JACS is reasonably fast by flagship standards, so switching journals to save a few weeks rarely pays. The better lever is the transfer path: if the desk decision says the paper belongs in a specialist ACS title, accepting the transfer keeps your suggested reviewers and files and avoids a cold restart. Angewandte Chemie is the usual non-ACS alternative for authors who want a similar audience, and the JACS journal profile sets out scope and fit in one place.

Evidence basis: We rechecked the ACS author guidelines for JACS on October 8, 2026, and paired them with the SciRev community timings above. The ACS text controls what JACS requires. Which omissions cost days is Manusights judgment built on that text, and it is not a forecast of the decision on your paper.

Nothing on the ACS page promises speed. What it does promise is order: complete, reviewable manuscripts are processed and assigned first. Read that way, a fast desk decision usually means a paper the Associate Editor could judge in one sitting, in either direction.

Two stop signals are worth taking literally. If the honest one-line claim of your paper names a single reaction class and no consequence outside it, the transfer suggestion is the likely outcome and a specialist ACS journal will be faster. And if your Article mostly adds data to your own earlier Communication, the guidelines say it will be declined without a new conceptual step, so do not spend the six weeks finding out.

Before you upload, a JACS review timeline and scope check reads the abstract, methods and references the way a first-pass editor would. That scan is free, finishes in roughly one to two minutes without a card, and gives back a submission-risk signal, the top blocker, and journal-fit context for JACS.

Be patient if:

• Your paper has been "Under Review" for less than 6 weeks, that's normal for JACS

• You submitted during a major conference season (ACS Spring/Fall meetings) when AEs and reviewers are traveling

• The paper requires reviewers from a narrow subfield where qualified experts are limited

• You've received a major revision decision and are using the 30 days (Article) or 21 days (Communication) ACS allots for new synthesis or mechanistic experiments.

Follow up if:

• "Under Editorial Review" has lasted more than 4 weeks without a status change, the desk assessment may have stalled

• "Under Review" has exceeded 8 weeks, reviewer tardiness is the most likely explanation

• You received a revision decision more than 2 weeks ago but haven't received the reviewer comments

• Your revised manuscript has been back with the journal for more than 4 weeks without a decision.

A polite email to the Associate Editor handling your paper is appropriate once you've crossed these thresholds. Don't escalate to the Editor-in-Chief unless the AE is unresponsive after two follow-ups.
