Quality control
How we test every lot
Consistency starts with verification. Every batch that leaves our facility is tested by an independent third-party laboratory for purity, identity, and basic physical properties before it is released for sale.
HPLC purity analysis
Each lot is analyzed by reversed-phase high-performance liquid chromatography to confirm purity and detect impurities. Our standard release threshold is ≥98–99% depending on the compound.
Mass spectrometry identity
MALDI-TOF or ESI-MS is used to verify molecular weight and confirm that the synthesized sequence matches the expected identity.
Appearance & solubility
Lyophilized cakes are inspected for color, clarity after reconstitution, and dissolution behavior against an internal reference standard.
Certificate of Analysis
Lot-specific COAs are available for download from your account after shipment. Each COA includes test date, results, and the third-party lab identifier.
