Certificates of Analysis

Every lot, on the record.

Each vial carries a lot number. That number ties it to the analysis performed on the batch it came from — independent first, then ours on arrival.

Getting your certificate

The lot number is printed on the vial label and appears on your order confirmation. Two routes to the certificate for it:

  1. In your account. Certificates are filed against the order they shipped with, so the one you open is the one for the vial in your hand.
  2. Ask us. Send the lot number and we will send the certificate back.

What’s on a certificate

  • The compound and the lot it identifies
  • Purity by HPLC, stated as a percentage
  • Identity confirmed by mass spectrometry
  • The laboratory that performed the analysis
  • The date the analysis was run

Two analyses stand behind every lot: one from a laboratory with no stake in the result, and then our own.
