(S)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)methanesulfonamide CAS 187831-22-7

Description

The occurrence of (S)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)methanesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)methanesulfonamide (CAS 187831-22-7), a certified reference material (molecular formula C9H12ClNO3S, MW 249.71 g/mol) for analytical method development and quality control.

(S)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)methanesulfonamide (C9H12ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
