The molecular framework of 3,4-Dichlorobenzene-1-sulfonyl chloride 3,4-dichloro-benzenesulfonylchlorid 3,4-dichlorobenzenesulfonyl chloride 3,4-dichlorobenzenesulfonyl chloride, 95 % 3,4-dichlorobenzenesulphonyl chloride 3,4-dichlorobenzenesulphonyl chloride 98% 3,4-dichlorophenylsulfonyl chloride 98-31-7 benzenesulfonyl chloride, 3,4-dichloro- (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.
As a certified reference material (CRM), 3,4-Dichlorobenzene-1-sulfonyl chloride 3,4-dichloro-benzenesulfonylchlorid 3,4-dichlorobenzenesulfonyl chloride 3,4-dichlorobenzenesulfonyl chloride, 95 % 3,4-dichlorobenzenesulphonyl chloride 3,4-dichlorobenzenesulphonyl chloride 98% 3,4-dichlorophenylsulfonyl chloride 98-31-7 benzenesulfonyl chloride, 3,4-dichloro- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
