Chemical Structure
Description
2,6-Dichloro-3-methylbenzene-1-sulfonyl chloride (CAS 64063-38-3) is a high-purity analytical reference standard with the molecular formula C7H5Cl3O2S and a molecular weight of 259.54 g/mol.
2,6-Dichloro-3-methylbenzene-1-sulfonyl chloride (C7H5Cl3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2,6-Dichloro-3-methylbenzene-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.
