Chemical Structure
Description
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.
CATO supplies 2,6-Dimethylphenyl 2-[N-(2,4-difluorophenyl)benzenesulfonamido]acetate (CAS 343373-97-7), a certified reference material (molecular formula C22H19F2NO4S, MW 431.45 g/mol) for analytical method development and quality control.
The molecular framework of 2,6-Dimethylphenyl 2-[N-(2,4-difluorophenyl)benzenesulfonamido]acetate (C22H19F2NO4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
