CATO supplies 2,5-DICHLOROBENZENE-1-SULFONYL CHLORIDE 2,5-DICHLOROBENZENESULPHONYL CHLORIDE 2,5-Dichlorobenzenesulfonyl chloride 5402-73-3 AS03520 LABOTEST-BB LT03331296 LABOTEST-BB LT03379769 LABOTEST-BB LTBB005068 OTAVA-BB 1179428 (CAS 5402-73-3), a certified reference material (molecular formula C6H9Cl3O2S, MW 251.56 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-DICHLOROBENZENE-1-SULFONYL CHLORIDE 2,5-DICHLOROBENZENESULPHONYL CHLORIDE 2,5-Dichlorobenzenesulfonyl chloride 5402-73-3 AS03520 LABOTEST-BB LT03331296 LABOTEST-BB LT03379769 LABOTEST-BB LTBB005068 OTAVA-BB 1179428 (C6H9Cl3O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
