Chemical Structure

2,6-Dichloro-4-sulfamoylbenzenesulfonyl chloride CAS 19797-72-9 chemical structure

Description

2,6-Dichloro-4-sulfamoylbenzenesulfonyl chloride (C6H4Cl3NO4S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.

2,6-Dichloro-4-sulfamoylbenzenesulfonyl chloride (CAS 19797-72-9), molecular formula C6H4Cl3NO4S2 and molecular weight 324.59 g/mol, is a CATO reference standard with documented purity and traceability.

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.
