Quality
Every lot is tested by an independent laboratory before it reaches the shelf, and the certificate travels with the product.
Independent testing
Identity and purity are established by a third-party laboratory, not in-house. The result is issued as a certificate of analysis tied to a specific lot number, and that is the document we publish and ship.
What the certificate states
- Lot number and compound identity
- Measured purity for that lot
- Molecular formula, molecular mass and CAS registry number
- Appearance and the analytical method used
We do not reproduce identity data on product pages. A number typed onto a web page can drift away from the material in the vial. The certificate cannot.
Handling and storage
Material ships sealed, in protective packaging, with the lot documentation. Storage conditions for the specific lot are stated on its certificate. We do not publish preparation, solvent or administration guidance of any kind.
Requesting a certificate
Ask us for the current lot certificate for any line and we will send it. See certificates of analysis.
Every lot, every time
- Third-party laboratory, not in-house
- One certificate per lot, tied to the lot number on the vial
- Sealed vials, protective packaging
- Identity data on the certificate, never retyped on a web page
