3-(CHLOROSULFONYL)BENZOIC ACID 3-(CHLOROSULPHONYL)BENZOIC ACID 3-CARBOXYBENZENESULFONYL CHLORIDE 3-CARBOXYLBENZENESULFONYL CHLORIDE 3-Chlorosulfony benzoic acid 4025-64-3 AKOS AKM00830 AKOS BB-9469 AKOS BBS-00006994 AS00820 BENZOIC ACID, 3-(CHLOROSULFONYL)- M-(CHLOROSULFONYL) BENZOIC ACID TIMTEC-BB SBB003351 (C7H11ClO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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.
