Methyl 3-(2-{[2-(3-chlorobenzamido)phenyl]sulfanyl}acetamido)thiophene-2-carboxylate CAS 477887-61-9

Description

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.

CATO supplies Methyl 3-(2-{[2-(3-chlorobenzamido)phenyl]sulfanyl}acetamido)thiophene-2-carboxylate (CAS 477887-61-9), a certified reference material (molecular formula C21H17ClN2O4S2, MW 460.95 g/mol) for analytical method development and quality control.

The molecular framework of Methyl 3-(2-{[2-(3-chlorobenzamido)phenyl]sulfanyl}acetamido)thiophene-2-carboxylate (C21H17ClN2O4S2) 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.
