Chemical Structure
Description
The molecular framework of 2-Bromo-4-chloro-1-methanesulfonylbenzene (C7H6BrClO2S) 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).
2-Bromo-4-chloro-1-methanesulfonylbenzene (CAS 1782806-79-4) is a high-purity analytical reference standard with the molecular formula C7H6BrClO2S and a molecular weight of 269.54 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Bromo-4-chloro-1-methanesulfonylbenzene 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.
