Chemical Structure

N-(2-aminoethyl)-4-chloro-2-methylbenzene-1-sulfonamide hydrochloride CAS 1603725-48-9 chemical structure

Description

The occurrence of N-(2-aminoethyl)-4-chloro-2-methylbenzene-1-sulfonamide hydrochloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-(2-aminoethyl)-4-chloro-2-methylbenzene-1-sulfonamide hydrochloride (CAS 1603725-48-9), a certified reference material (molecular formula C9H13ClN2O2SHCl, MW 285.18 g/mol) for analytical method development and quality control.

N-(2-aminoethyl)-4-chloro-2-methylbenzene-1-sulfonamide hydrochloride (C9H13ClN2O2SHCl) contains an amide group, a sulfone group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
