Chemical Structure
Description
The molecular framework of (S)-2-((tert-Butoxycarbonyl)amino)-3-(4-(methylthio)phenyl)propanoic acid (C15H21NO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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-((tert-Butoxycarbonyl)amino)-3-(4-(methylthio)phenyl)propanoic acid (CAS 88170-86-9) is a high-purity analytical reference standard with the molecular formula C15H21NO4S and a molecular weight of 311.40 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.
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.
