ABOUT CERTIFICATES OF ANALYSIS
4 ITEMSWhat is a certificate of analysis (COA)?
A certificate of analysis is a lab document tied to a specific production lot. It records the analytical results for that batch — identity and purity by the stated method — so a buyer can match a physical vial to its own test record rather than a brand-wide sample.
How do I verify a specific lot?
Search this library by compound name or lot number. Each vial's label states its lot; entering that lot returns the matching certificate for the batch you received.
How is each lot tested?
Every batch is tested by HPLC with mass-spectrometry confirmation before it is listed — HPLC for purity, MS for identity. The figure on the label is the value returned for that lot.
Is a certificate of analysis included for every batch?
Yes. A certificate is filed for every batch we sell and is searchable here by lot. If you cannot match a vial to a record, contact our team.
