What a COA is
A Certificate of Analysis (COA) is a document issued by a manufacturer or third-party lab that records the analytical testing performed on a specific batch of material. This article walks through the fields you will typically see on a research-compound COA.
Common COA sections
- Compound identity
- Batch / lot number
- Purity (often by HPLC)
- Mass-spectrometry confirmation
- Endotoxin or microbial testing where applicable
What to verify
Researchers should verify the lab, the date of testing, and that the lot number on the COA matches the lot number on the product.
