Confidence Starts with Transparency.
Nothing goes on sale on a supplier's word. Every lot moves through the same four checks, and the certificate for that exact batch is published before the product page goes live.
Four Checks Before a Lot Becomes a Listing
Intake & Identity
Mass spectrometry confirms the compound is what the supplier says it is before anything else is measured. A mismatch ends the lot here — it never enters inventory.
Purity by HPLC
Reverse-phase HPLC runs the material against a reference standard. The measured figure is what we publish, not a rounded marketing number.
Second-Lab Confirmation
The retained sample goes to an unaffiliated lab with no stake in the result. Both certificates are published side by side.
Lot-Linked Publication
The lot number on your vial resolves to one certificate — searchable publicly and archived against your orders.
Search a lot number to read its certificate before you buy, or find it in your account afterward. Your order records →
Stored Right. Guaranteed.
Compounds ship as lyophilized powder, shelf-stable and sealed — no cold chain required. Keep it lyophilized at −20°C away from light; once reconstituted, refrigerate and use it within the window on the product page.
If a lot doesn't match its certificate, we replace it or refund it — no argument.
