4-(((2,6-Dichlorophenyl)sulfonamido)methyl)benzoic acid CAS 690645-97-7

Description

4-(((2,6-Dichlorophenyl)sulfonamido)methyl)benzoic acid (CAS 690645-97-7), molecular formula C14H11Cl2NO4S and molecular weight 360.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 4-(((2,6-Dichlorophenyl)sulfonamido)methyl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
