Documentation

Read the report before you read the label.

Anyone can print a purity figure on a vial. What matters is whether the number can be traced back to an instrument run, a lot number and a report you can open yourself.

Every compound we ship carries a lot number on the label. That number maps to a certificate of analysis issued by an independent laboratory, with the chromatogram and the verification key published in our database.

Open the COA database

What a COA can tell you

  • Purity as a percentage of peak area
  • Identity confirmation by mass
  • The method used and its limits
  • Which lot the result belongs to
  • When the analysis was run
