USP <621>
HPLC purity
Reverse-phase HPLC quantifies primary peak area and screens for related substances and process impurities on every release lot.
Documentation & Testing
Every lot, every test —
on file, in one place.
We do not ask researchers to take our word for analytical quality — we ship the analytical record with the vial. Browse the lot-level Certificate of Analysis (CoA) library below: HPLC purity, mass-spec identity, sterility (USP <71>) and bacterial-endotoxin (USP <85>) screening on every released lot.

Our quality procedures
Six checks before a lot is released.
Each released lot passes the procedures below before it leaves QA. The results are recorded in the CoA that ships with the order.
LC-MS
Mass-spec identity
Mass spectrometry confirms molecular identity by exact mass. The acquired spectrum is filed in the CoA against the master reference.
USP <71>
Sterility
Microbial-growth sterility screening is performed on every released lyophilized lot by an accredited microbiology partner.
USP <85>
Bacterial endotoxin
Bacterial endotoxin testing (LAL kinetic) is run per lot and the result is documented as endotoxin units per vial in the CoA.
ICH Q1A
Accelerated stability
Accelerated stability runs simulate shipping and storage stress so the lot you receive performs identically to the lot we released.
Internal QA
Lot-to-lot benchmark
Every lot is benchmarked against a master reference for retention time and mass identity so analytical work converges order to order.
Need a different lot, prior CoA, or raw data?
QA records — including HPLC chromatograms and prior-lot CoAs — are kept on file and available on request for qualified research customers.
