Certificates
of Analysis.

In research supply the vial is interchangeable. What is not interchangeable is the evidence that the contents match the label.

Issued per production lot

Analysis is performed on the production lot rather than extrapolated from a prior batch. A certificate carried over from a previous lot is paperwork, not evidence, and the gap only surfaces when it matters.

Provided to approved accounts

Certificates are released to verified wholesale accounts. Every shipment carries the certificate for its specific lot, and prior certificates are retained rather than replaced for the life of the account.

What a certificate records

• Compound identity
• Purity established by HPLC
• Lot reference
• Date of analysis
• Method of analysis
