- HPLC-UV at 218nm — every production batch, minimum threshold 99.0%.
- Mass spectrometry (LC-MS) confirms molecular identity before any lot ships.
- Intertek and Eurofins issue all COAs — not Fraction Research. Independent by design.
All COA documents are publicly searchable by lot number. Enter any lot number from your shipment to retrieve the full analytical report.
