4-Amino-N-(4,5-dimethylpyrimidin-2-yl)benzenesulfonamide CAS 4462-43-5 chemical structure

Description

The occurrence of 4-Amino-N-(4,5-dimethylpyrimidin-2-yl)benzenesulfonamide is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Amino-N-(4,5-dimethylpyrimidin-2-yl)benzenesulfonamide (CAS 4462-43-5), a certified reference material (molecular formula C21H41NO6, MW 403.55 g/mol) for analytical method development and quality control.

Based on its molecular formula C21H41NO6, 4-Amino-N-(4,5-dimethylpyrimidin-2-yl)benzenesulfonamide contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 403.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
