Independent laboratories
A certificate is shown only when it comes from an independent laboratory and carries a report number.
Identity and purity
The laboratory identifies each compound by mass spectrometry and reports purity by HPLC.
Lot matching
Each certificate is matched to the lot being sold.
How to verify a report
Each certificate lists the laboratory and its report number. Where the laboratory provides a verification link, use it to confirm the report with the laboratory.
Current status
Awaiting independent reports
Every compound is listed as COA pending until an independent report matched to its lot is on file. Certificates are posted in the COA Library as they are received.
