Quality & testing
How a lot earns its listing.
Nothing goes on the shelf until an independent lab has tested it and the certificate is published.
The process
From synthesis to your bench.
- 01
Specification
Made to a ≥98% purity spec
Every compound is manufactured to a minimum 98% HPLC purity specification before it reaches us.
- 02
Independent testing
Tested by a third-party lab
Each batch is sent to an independent U.S. laboratory. Purity is measured by HPLC and identity is confirmed by mass spectrometry.
- 03
Documentation
A certificate for every batch
The lab issues a certificate of analysis for each batch, and we publish it so you can review the results before you order.
- 04
Release
Sealed and stored right
Only batches that meet spec are released. Vials are sealed and stored cold, dry and away from light.
- 05
Fulfilment
Packed plain, shipped fast
Orders ship from the United States in plain, tamper-evident packaging, with tracking on every shipment.
