Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-bromo-4-methanesulfonylbenzene-1-sulfonyl chloride (CAS 1603381-94-7), a certified reference material (molecular formula C7H6BrClO4S2, MW 333.61 g/mol) for analytical method development and quality control.
The molecular framework of 2-bromo-4-methanesulfonylbenzene-1-sulfonyl chloride (C7H6BrClO4S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-bromo-4-methanesulfonylbenzene-1-sulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
