Three checks before a lot is released
Identity confirmed
Mass spectrometry against the expected molecular weight, before a lot is released. A lot that does not match never reaches inventory.
Purity determined
Reverse phase HPLC by an independent laboratory. We publish the figure they report, not a specification target.
Lot traceable
Every vial carries a lot number that resolves to the certificate for that exact batch, with the laboratory and date named.

Questions, answered
All questionsWho is eligible to purchase?
Qualified researchers, laboratories, universities, and commercial research entities purchasing for in vitro laboratory research.
Do you provide certificates of analysis?
Yes, for every lot. Each names the laboratory, the method, the date of analysis, and the result.
Why do listings not describe what compounds do?
Because a certificate can establish what a material is, not what it does. We publish analytical identity and purity, and leave the literature to speak for itself.
Can I order on a purchase order?
Yes. Institutional purchase orders and invoiced accounts are welcome. Contact us with your institution details.
Start with the certificate
Browse the catalogue, check the analytical record for any lot, and decide from the documentation rather than the marketing.
