What we mean
when we say
research grade.

Most suppliers will ship you a vial. We ship you a paper trail. Every batch moves through a four-gate release process — and we publish the result of all four.

ISO 9001 referencedUSP <1086>
01

Triple-pass HPLC

Every batch is verified by reverse-phase HPLC, mass spectrometry, and endotoxin screening before release.

02

Documented chain

Synthesis origin, courier handoff, and storage temperature recorded from synthesis to delivery.

03

Open COA

A signed Certificate of Analysis is attached to every order. No paywalls, no redactions, no asterisks.
