What this document is
A certificate of analysis records what an independent laboratory measured in a sample drawn from a specific production batch. It states the compound identified, the purity measured, the analytical method used, and the date of analysis, and it is signed by the laboratory that performed the work — not by the seller. We publish every certificate we receive, including the batch number, so the lot on a vial can be matched against the document covering it.
