CATO supplies (2S,3S)-2-((2S,3S)-2-(((Benzyloxy)carbonyl)amino)-3-methylpentanamido)-3-methylpentanoic acid (CAS 42538-01-2), a certified reference material (molecular formula C20H30N2O5, MW 378.46 g/mol) for analytical method development and quality control.
Structurally, (2S,3S)-2-((2S,3S)-2-(((Benzyloxy)carbonyl)amino)-3-methylpentanamido)-3-methylpentanoic acid (C20H30N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 378.46 g/mol, it falls into the moderately-high-molecular-weight range. 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 (2S,3S)-2-((2S,3S)-2-(((Benzyloxy)carbonyl)amino)-3-methylpentanamido)-3-methylpentanoic 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.
