ACS Technical Standard

The Complete ACS Formatting Guide

The official standard for Chemistry, Materials Science, and Biochemistry. Verified against official American Chemical Society Style Guide requirements.

Official ACS Guidelines

What is ACS (American Chemical Society) Format?

The ACS Style Guide is the official standard for manuscripts submitted to American Chemical Society journals. It's used by chemists, chemical engineers, materials scientists, and researchers in related fields worldwide. The 3rd edition (2006) is current, with online updates for new requirements.

ACS format has unique requirements distinct from APA/MLA: superscript citation numbers, specific chemical nomenclature, mandatory safety statements, and journal-specific variations. Missing any requirement can lead to desk rejection.
