Purity, identity and endotoxin results are published as a Certificate of Analysis you can read before you order — matched to the batch ID printed on the vial.
Each listing shows its batch purity and endotoxin result on the card — tap either to open the certificate.
Pick a compound and a batch to pull its certificate. Already have a vial? Match the batch reference on the label.
Three assays before anything ships. A batch that fails any one of them is destroyed, not relabelled.
High-performance liquid chromatography measures the target compound against impurities. Our shipping floor is >99%.
Confirms molecular weight and structure, so mislabelled or substituted material is caught before it reaches a vial.
Limulus amebocyte lysate testing detects bacterial endotoxins. Batches with detectable endotoxins do not ship.
Sterility, heavy metals and fentanyl screening are being added to the standard panel through an accredited lab.
Every vial carries a lot code that links to the certificate for that production run. Not a generic COA, not a reused supplier document, not a sibling batch.
