(S)-4-(((Benzyloxy)carbonyl)amino)-5-(((S)-1-carboxy-2-(1H-indol-3-yl)ethyl)amino)-5-oxopentanoic acid (CAS 73170-51-1) is a high-purity analytical reference standard with the molecular formula C24H25N3O7 and a molecular weight of 467.47 g/mol.
(S)-4-(((Benzyloxy)carbonyl)amino)-5-(((S)-1-carboxy-2-(1H-indol-3-yl)ethyl)amino)-5-oxopentanoic acid (C24H25N3O7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
