What a certificate of analysis shows
A certificate of analysis (CoA) is the laboratory report for a specific batch. Ours records the compound tested, the batch number, the analysis date, the method used, the measured purity by HPLC and the identity confirmation by mass spectrometry.
How to match a certificate to your vial
The batch number printed on the vial label matches the batch number on the product page and on the certificate. If the three do not agree, contact us and do not use the vial.
Purity thresholds
We do not list a batch below 98% measured purity. Most batches sit between 99.0% and 99.8%, and the measured figure, not a target figure, is what appears on the product page.
Handling and storage
- Store sealed lyophilised vials at -20C for long-term stability.
- 2-8C refrigeration is acceptable for short periods.
- Protect vials from direct light and repeated temperature cycling.
- Once reconstituted, refrigerate and use within the period stated on the certificate.
