Chemical Structure

N,N,4-Trimethyl-3-nitrobenzenesulfonamide CAS 96-57-1 chemical structure

Description

CATO supplies N,N,4-Trimethyl-3-nitrobenzenesulfonamide (CAS 96-57-1), a certified reference material (molecular formula C9H12N2O4S, MW 244.27 g/mol) for analytical method development and quality control.

N,N,4-Trimethyl-3-nitrobenzenesulfonamide (C9H12N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
