H-Ala-Pro-Val-5-[(2-aminoethyl)amino]-naphthalene-1-sulfonic acid (CAS 396077-59-1), molecular formula C25H35N5O6S and molecular weight 533.64 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, H-Ala-Pro-Val-5-[(2-aminoethyl)amino]-naphthalene-1-sulfonic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 533.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures H-Ala-Pro-Val-5-[(2-aminoethyl)amino]-naphthalene-1-sulfonic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
