Chemical Structure
Description
The occurrence of N-(4-Bromophenyl)-2-{N-[2,4-dichloro-5-(2-methoxyethoxy)phenyl]4-chlorobenzenesulfonamido}acetamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-(4-Bromophenyl)-2-{N-[2,4-dichloro-5-(2-methoxyethoxy)phenyl]4-chlorobenzenesulfonamido}acetamide (CAS 338967-66-1), a certified reference material (molecular formula C23H20BrCl3N2O5S, MW 622.74 g/mol) for analytical method development and quality control.
The molecular framework of N-(4-Bromophenyl)-2-{N-[2,4-dichloro-5-(2-methoxyethoxy)phenyl]4-chlorobenzenesulfonamido}acetamide (C23H20BrCl3N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
