Quality Assurance

Quality and documentation

Our certificates of analysis are being re-checked, and we are not publishing them or making testing claims until that is finished. Ask about the documentation for the batch we would ship before you order.

Check any certificate yourself

A real certificate names its laboratory and carries a verification key you can check with that laboratory directly. Here’s how.

Batch documentation

Ask before you order and we will tell you what documentation exists for the batch we would ship.

Cold-chain handling

Lyophilised and shipped to preserve stability, with storage guidance supplied for every compound.

Standards

Where our compounds come from#

Our compounds are made at a facility we own and operate jointly with our manufacturing partner, and analysed in our own laboratory.

We have the instruments to test our own material, and we do.

What we will and won’t claim#

We do not promise a purity figure in advance, and we do not describe a batch as tested unless we can show you the certificate for it. For laboratory research use only — not for human consumption.

Purity	Reported only from a certificate for that specific batch, as measured — never stated as a minimum
Analytical method	Only what the certificate itself states. We do not add a method to a document that does not name one
Certificates	Being re-checked; ask us about a specific batch
Intended use	Laboratory research use only (RUO)

HPLC, the technique behind a purity percentage, separates a sample into its individual components so the target compound can be measured against any impurities. The figure it reports is area percent — the main peak’s share of the UV-absorbing material the detector saw, not a mass fraction of the vial. That is why the quantity result is reported separately. What a purity figure actually means.
