CATO supplies (S)-3-(((Benzyloxy)carbonyl)amino)-4-((S)-2-(tert-butoxycarbonyl)pyrrolidin-1-yl)-4-oxobutanoic acid (CAS 4583-13-5), a certified reference material (molecular formula C21H28N2O7, MW 420.46 g/mol) for analytical method development and quality control.
Structurally, (S)-3-(((Benzyloxy)carbonyl)amino)-4-((S)-2-(tert-butoxycarbonyl)pyrrolidin-1-yl)-4-oxobutanoic acid (C21H28N2O7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 420.46 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
