(2S,3S)-3-(((Benzyloxy)carbonyl)amino)-2-hydroxy-4-phenylbutanoic acid (CAS 62023-59-0), molecular formula C18H19NO5 and molecular weight 329.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2S,3S)-3-(((Benzyloxy)carbonyl)amino)-2-hydroxy-4-phenylbutanoic acid (C18H19NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
