Match the lot number printed on your vial to its Certificate of Analysis. A document on file records what was tested for that lot; it does not establish approval of any kind.
1. Find the lot number on the vial label.
2. Open the COA library below and locate that lot.
3. Check that the compound, the lot number and the test date match the vial you received.
Reports state the analytical methods used for that lot. HPLC and mass spectrometry answer different questions: one speaks to purity by peak area, the other to identity by mass. Read the report rather than assuming a single figure covers both.
If the report for your lot is not yet in the library, email [email protected] with the compound, the lot number and your order number, and we will send it to you.
Reports are published here as each lot is released. If a lot is missing, request it by email and we will send the document for that lot.
Certificates are published here as each lot is released. Search by compound or by the lot number printed on your vial.

Find the certificate for your lot and read the original report. Each entry links to one lot record and its document. A document on file records what was tested for that lot; it does not establish approval of any kind.
This certificate is a scanned document, so its figures cannot be listed here. Open the report to read the results as the laboratory issued them.
