(2S)-2-{[(3-Oxo-3,4-dihydro-1(2H)-quinoxalinyl)carbonyl]amino}-3-phenylpropanoic Acid (CAS 1173681-44-1) is a high-purity analytical reference standard with the molecular formula C18H17N3O4 and a molecular weight of 339.35 g/mol.
The molecular framework of (2S)-2-{[(3-Oxo-3,4-dihydro-1(2H)-quinoxalinyl)carbonyl]amino}-3-phenylpropanoic Acid (C18H17N3O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
