Chemical Structure
Description
(S)-2,3-Bis(((benzyloxy)carbonyl)amino)propanoic acid (CAS 65621-26-3) is a high-purity analytical reference standard with the molecular formula C19H20N2O6 and a molecular weight of 372.37 g/mol.
The molecular framework of (S)-2,3-Bis(((benzyloxy)carbonyl)amino)propanoic acid (C19H20N2O6) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
