Certificates of analysis
Every lot, on paper.
Each batch we release is documented on a signed certificate of analysis from an independent US laboratory. Here’s what’s on it, and how to pull the one matching your vial.
What’s on every COA
- RP-HPLC purity against the ≥99% release floor, with the chromatogram
- Identity confirmed by ESI mass spectrometry against the expected mass
- Endotoxin by LAL, water content by Karl Fischer, and net peptide content
- Lot number, assay date, and retest date, signed off by QC release
Independent, not in-house
Analysis is performed by a third-party laboratory and reported on its own letterhead. We don’t grade our own work.
Matched to your vial
Every vial’s printed lot number resolves to the COA for its physical lot — not a generic sample. Use batch lookup to confirm a lot number any time.
