Chemical Structure

N-(2-(3-bromobenzoyl)-4,5-dimethoxyphenyl)-4-methylbenzenesulfonamide CAS 373370-93-5 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-(3-bromobenzoyl)-4,5-dimethoxyphenyl)-4-methylbenzenesulfonamide.

CATO supplies N-(2-(3-bromobenzoyl)-4,5-dimethoxyphenyl)-4-methylbenzenesulfonamide (CAS 373370-93-5), a certified reference material (molecular formula C22H20BrNO5S, MW 490.37 g/mol) for analytical method development and quality control.

The molecular framework of N-(2-(3-bromobenzoyl)-4,5-dimethoxyphenyl)-4-methylbenzenesulfonamide (C22H20BrNO5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
