Every batch tested. Every COA matched.
Credibility in this space comes down to one thing: can you trust what's in the vial. Here's exactly how we earn that trust.
HPLC purity
High-performance liquid chromatography quantifies purity for every production lot. We publish the result, typically >98-99%, directly on the listing.
Mass-spec identity
Mass spectrometry confirms the compound's molecular identity against its expected mass, so you know exactly what's in the vial.
Endotoxin screen
Lots are screened for bacterial endotoxin to a documented threshold, supporting clean, reproducible bench work.
Stability & cold-chain
Compounds are lyophilized and dispatched insulated with cold packs, preserving integrity from our facility to yours.
What “batch-matched COA” means
A lot of suppliers show a certificate of analysis that has nothing to do with the vial you receive. We don't. The COA referenced on each product page corresponds to the exact lot number printed on your label, so you can cross-check the paperwork against the physical product the moment it arrives.
Need the full PDF for your records or institutional documentation? It's linked on every product page, and our team can re-send any batch's certificate on request.
The batch on your label always matches the batch on the COA.
Identity, purity, and endotoxin results, tied to your lot, not a stock sample.
