Documentation at the batch level.
A certificate is only as good as the testing behind it. Here is how Cendrix qualifies materials, what we test, and how we draw the line between identity, purity, and biological activity.
Look up any released lot.
Enter the lot number printed on your vial or packaging to retrieve the applicable documentation.
Public verification is read-only. Full COA download requires a verified researcher account.
Supplier qualification
Suppliers are evaluated against documented identity, purity, and traceability requirements before any material is released into our catalog.
Identity confirmation
Molecular identity and chemical purity are separate questions. We confirm identity using LC-MS, MALDI-MS, or comparable methods appropriate to the compound.
Purity testing
HPLC purity is one input among several. It does not establish potency, sterility, or biological activity, and we never present it as if it did.
Quantity verification
We distinguish gross vial mass from peptide content, purity, water content, and counterion content, and present each separately on the certificate.
Independent testing
Each certificate clearly indicates which testing was performed internally and which was performed by a qualified third-party laboratory.
Certificate verification
Researchers can retrieve the certificate of analysis for any released lot using the lot number printed on the vial and packaging.
Recall & complaints
