Certificate of Analysis (COA)

A Certificate of Analysis (COA) is a batch-level quality document listing assay results, impurities and identity fields (often including CAS) for a specific production lot of a chemical.

Buyers should match COA product name and CAS to the invoice and packing list. Request a sample COA with the quote when purity or impurities are critical. See our free COA & SDS checklist resource.
