Certificates of Analysis

What the report contains

• HPLC-UV purity — the main-peak area percentage at 220 nm. Every released lot meets or exceeds the purity stated on its product page.
• Chromatogram — the full trace, so you can inspect secondary peaks yourself.
• Mass spectrometry — observed mass versus theoretical mass, confirming the compound’s identity.
• Lot metadata — synthesis date, analysis date, and the testing laboratory.
