COA database

Every vial carries a lot number. That number identifies the batch and links it to the certificate of analysis issued for it by an independent laboratory.

How to check your lot

1. Read the lot number printed on the vial label.
2. Open the report key shown on the product page for that compound.
3. Enter the key on the issuing laboratory's verification page.
4. Match the lot number, the compound name and the analysis date.

What the report contains

• Purity as a percentage of peak area, with the chromatogram
• Identity confirmation by mass spectrometry
• The analytical method and its limits
• The lot analysed and the date of analysis

A certificate covers the specific lot it was issued for. Results do not transfer between batches, and we do not publish a single report as representative of every vial we ship.

Reports that are not yet published

If a lot is awaiting analysis, the product page says so. We do not substitute an older report to fill the gap. Email us with the lot number and we will tell you where it stands.
