- Molecular formula — C14H22CuN6O4
- Molar mass — 401.9 g/mol
- CAS — 89030-95-5
Supplied as a lyophilized powder in a sealed glass vial. Store at −20 °C, desiccated and protected from light.
Peptides of this class are supplied as acetate or TFA salts, so gross vial weight exceeds net peptide content. The net content figure on our certificate is the peptide mass, measured gravimetrically.
On stoichiometry. A 2:1 peptide-to-copper complex (bisprezatide copper, CAS 130120-56-8, 742.3 g/mol) is a different substance and is sometimes returned first by chemical databases. This product is the 1:1 complex.
Each lot is tested by an independent laboratory for HPLC purity and gravimetric net content. The report is published on this page and readable before purchase.
