Certificate of Analysis (COA)

A Certificate of Analysis (COA) is a document issued by a testing laboratory that records the results of the analyses run on a specific lot of a compound — typically identity, purity, and content, along with the test methods, date, and the lab that performed them.

A trustworthy COA is per-batch: it is tied to the exact lot number printed on the vial, not a generic sample. That lets a researcher confirm that the material in hand matches what was tested, rather than relying on a shared or representative certificate.

At Renova, every lot ships with its own COA showing identity by mass spectrometry, purity by HPLC, and a unique lot number that can be verified independently.
