If you have ever cleaned up references for a chemistry paper, you know the tiny formatting problems add up fast.
ACS references look simple until you have to fix 40 of them at once: author initials, journal abbreviations, year/volume/pages order, DOI links, patent numbers, website access dates, and in-text citation style. I built a small free tool to make that cleanup workflow less painful:
Free ACS Citation Generator for Chemistry Papers
This post walks through the workflow I designed around it and the implementation decisions behind the tool.
The problem I wanted to solve
Most citation tools are broad. They support APA, MLA, Chicago, IEEE, and a lot of general academic formats. That is useful, but chemistry writers often need a more specific workflow.
For ACS-style writing, the rough shape of a journal article reference is:
Author 1; Author 2. Article Title. Journal Name Year, Volume, Page-Page. https://doi.org/...
~~~
That leaves a lot of room for small errors:
- Authors pasted as full names instead of surname plus initials
- Journal titles left as full names when an abbreviation is expected
- DOI values pasted as raw strings instead of links
- Issue numbers included or omitted inconsistently
- Website references missing an access date
- Patents missing the country, number, or publication date
- Reference lists copied from multiple tools with mixed punctuation
I did not want to build another giant reference manager. I wanted a focused cleanup tool that helps with the common ACS reference formatting tasks students and researchers repeat every week.
## The cleanup workflow
The workflow I use is intentionally simple.
## 1. Start with a DOI when possible
For journal articles, DOI lookup is the fastest starting point. A DOI usually gives you the title, authors, journal, year, volume, issue, pages, and DOI URL.
In the tool, the DOI workflow tries public metadata first. If metadata is available, the fields are filled automatically. If lookup fails, the manual fields still work.
This is important because citation tools should fail gracefully. A missing DOI record should not block the user from building the reference.
## 2. Normalize the source type
ACS references are not all journal articles. The tool supports several chemistry writing cases:
- Journal articles
- DOI-based sources
- Patents
- Websites
- Books
- Conference papers
- Theses
- Preprints
- Datasets
The reason I split these into source types is that each one has different required fields. A patent needs inventors, patent number, country or patent office, and date. A website needs a URL and often an access date. A book needs publisher and place.
A single giant form would be messy, so the UI changes fields based on the selected source type.
## 3. Generate the reference, then run checks
After formatting the reference, the tool shows a small checklist. It catches common omissions such as:
- Missing authors or organization name
- Missing source title
- Missing publication year or date
- Missing journal name
- Missing locator information such as volume, pages, or DOI
- Missing URL or access date for web sources
This is not meant to replace a final human review. It is meant to stop the obvious mistakes before they get copied into a manuscript.
## 4. Build the reference list locally
A lot of citation cleanup happens in batches. You fix one reference, copy it, fix another, reorder the list, and then export.
The tool keeps a local reference list in the browser. No account is required, and the saved list stays local to the user's browser.
That design keeps the product lightweight. The core loop is:
1. Enter or import source metadata
2. Generate the ACS reference
3. Add it to the local list
4. Edit, copy, reorder, or delete items
5. Export when ready
## 5. Export in useful formats
Plain text is enough for many lab reports, but not for every workflow. So I added exports for:
- TXT for plain reference lists
- RTF for word processors
- BibTeX for LaTeX workflows
- RIS for reference managers like Zotero
The export step matters because the output should move easily into the place where the paper is actually being written.
## Implementation notes
The project is a static browser-based tool. The main behavior lives in JavaScript, with a source-type configuration that defines labels, routes, and fields.
A simplified version of the idea looks like this:
~~~js
const sourceTypes = {
journal: {
label: "Journal Article",
fields: ["authors", "title", "journal", "year", "volume", "issue", "pages", "doi"]
},
patent: {
label: "Patent",
fields: ["inventors", "title", "patentNumber", "country", "publicationDate"]
},
website: {
label: "Website",
fields: ["authors", "title", "site", "year", "url", "accessDate"]
}
};
~~~
Each formatter can focus on one source type instead of trying to make one universal citation function handle everything.
A simplified journal formatter might look like this:
~~~js
function formatJournalArticle(ref) {
return [
ref.authors + ".",
ref.title + ".",
ref.journal + " " + ref.year + ",",
ref.volume,
ref.pages ? ref.pages + "." : "",
ref.doi ? "https://doi.org/" + cleanDoi(ref.doi) : ""
]
.filter(Boolean)
.join(" ");
}
~~~
The real work is less about one clever function and more about lots of small formatting decisions:
- How to avoid double punctuation
- How to handle optional fields
- How to clean DOI input
- How to preserve author separators
- How to make missing fields visible without blocking manual entry
- How to export the same reference list into multiple formats
## Why I kept it free and browser-based
For this kind of utility, speed matters more than accounts. A chemistry student writing a lab report should not need to sign up just to clean a DOI reference.
So the tool is free to use, runs in the browser, and keeps reference-list data locally. That also makes it easier to maintain as a small independent project.
## A practical ACS cleanup checklist
When I clean a reference list now, I use this checklist:
1. Prefer DOI import for journal articles.
2. Confirm author names and initials.
3. Check whether the journal title should be abbreviated.
4. Confirm year, volume, issue, and page range.
5. Use DOI links consistently.
6. Add access dates for web pages that can change.
7. Keep patents, datasets, and preprints in their own source-type formats.
8. Export the final list and do one manual pass against the target journal or instructor requirements.
The last step is important. ACS-style examples are useful, but journal instructions and course requirements can still differ.
## What I would improve next
The next improvements I am thinking about are:
- Better journal abbreviation suggestions
- More batch DOI cleanup features
- Stronger examples for ACS in-text citations
- More edge-case tests for patents, datasets, and preprints
- A smoother bridge to Zotero and other reference managers
If you write chemistry papers, lab reports, or technical documents, I hope this saves a few minutes of reference cleanup.

I'm curious, how did you handle edge cases like formatting for multiple authors or affiliations in the citation generator?
