The chemistry preprint server.
At a Glance
| Publisher | a partnership of chemistry societies (ACS, RSC, GDCh, CCS, CSJ, and others) |
| Coverage | preprints across all areas of chemistry |
| Access | free to read and submit; moderated, not peer-reviewed |
| Regional | global. |
Our Take
ChemRxiv is chemistry’s dedicated preprint server, backed by the field’s major societies, and it’s where chemical research increasingly appears before journal publication — the early-signal layer for a discipline that adopted preprints later than physics or biology. The standard preprint caveat applies: moderated for scope, not correctness. Use it to track the chemistry frontier and to post your own work early; verify claims against the peer-reviewed version, and pair with PubChem/SciFinder for substance and reaction data.
Power Tips
- Add ChemRxiv to your scanning for early chemistry findings, tiering confidence as you would any preprint (Issue 4)
- when a ChemRxiv paper reports new substances or reactions, verify them in PubChem or SciFinder before relying on them.
