Science unchained.Assayed by lot. Published before sale.
Every compound is third-party assayed before its lot goes live, and the certificate is published against the number printed on the vial. Look it up before you buy — not after.

The paperwork comes first
Most suppliers publish a certificate on request. We publish it as a precondition of the lot going on sale — which means you can verify what you are buying before you spend anything.
Assayed per lot
Not per product, not per year. Each lot is independently assayed by HPLC and confirmed by mass spec, and the result is bound to that lot number for its lifetime.
Published, not on request
Certificates are public and linked from the product page. If a lot has no certificate on file it cannot be listed — the catalogue is gated on the document, not the other way round.
Traceable to the vial
The lot number on the vial in your hand resolves to the exact assay run, the date, and the analysing laboratory. No lookup table, no support ticket.
By category
New lots on the shelf
Every lot, on the record
Four checkpoints between a synthesis run and a listing. A lot that fails any one of them is quarantined and never reaches the catalogue.
Intake & quarantine
The lot is received, assigned an internal lot number, and held. Nothing is listed, photographed, or priced at this stage.
Independent assay
A sample is drawn and sent to a third-party laboratory for HPLC purity and mass-spec identity confirmation. We do not run our own numbers.
Certificate published
The returned certificate is uploaded and bound to the lot number. This write is what makes the lot listable — the catalogue reads the document, not a checkbox.
Release to catalogue
Stock is decremented against that specific lot from then on, so the certificate you read is the certificate for the vial you receive.
