A Certificate of Analysis (COA) is an official document issued by an analytical testing laboratory that confirms the identity, purity, and composition of a specific batch of material. COAs are standard documentation in pharmaceutical, chemical, and research supply industries. They provide objective, third-party verification that a compound matches its labeled specifications.

At Ascend Biolabs, we obtain COAs from independent testing laboratories for our research compounds. Each certificate is tied to a specific production batch, identified by a unique lot number, and documents the analytical methods used and results obtained during testing.
