Chemical Structure
Description
The molecular framework of (S)-2-((S)-2-Amino-3-phenylpropanamido)-3-(1H-imidazol-4-yl)propanoic acid (C15H18N4O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
(S)-2-((S)-2-Amino-3-phenylpropanamido)-3-(1H-imidazol-4-yl)propanoic acid (CAS 33367-37-2) is a high-purity analytical reference standard with the molecular formula C15H18N4O3 and a molecular weight of 302.33 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
