Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,5-Dichlorophenyl)-N-(methylsulfonyl)alanine.
CATO supplies N-(2,5-Dichlorophenyl)-N-(methylsulfonyl)alanine (CAS 1008229-92-2), a certified reference material (molecular formula C10H11Cl2NO4S, MW 312.17 g/mol) for analytical method development and quality control.
The molecular framework of N-(2,5-Dichlorophenyl)-N-(methylsulfonyl)alanine (C10H11Cl2NO4S) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
