Chemical Structure
Description
(S)-Methyl 2-(2-chlorophenyl)-2-(nitroso((2-(2-oxoethyl)thiophen-3-yl)methyl)amino)acetate (CAS CATO-C3D-26209) is a high-purity analytical reference standard with the molecular formula C16H15ClN2O4S and a molecular weight of 366.82 g/mol.
The molecular framework of (S)-Methyl 2-(2-chlorophenyl)-2-(nitroso((2-(2-oxoethyl)thiophen-3-yl)methyl)amino)acetate (C16H15ClN2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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.
