3-((4-(2-Chlorophenoxy)phenyl)sulfonamido)benzoic acid CAS 606944-47-2 chemical structure

Description

The occurrence of 3-((4-(2-Chlorophenoxy)phenyl)sulfonamido)benzoic acid is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-((4-(2-Chlorophenoxy)phenyl)sulfonamido)benzoic acid (CAS 606944-47-2), a certified reference material (molecular formula C19H14ClNO5S, MW 403.84 g/mol) for analytical method development and quality control.

3-((4-(2-Chlorophenoxy)phenyl)sulfonamido)benzoic acid (C19H14ClNO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
