Chemical Structure
Description
CATO supplies 4-(3-chloropropyl)benzene-1-sulfonyl chloride (CAS 7296-67-5), a certified reference material (molecular formula C9H10Cl2O2S, MW 253.15 g/mol) for analytical method development and quality control.
The molecular framework of 4-(3-chloropropyl)benzene-1-sulfonyl chloride (C9H10Cl2O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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).
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 4-(3-chloropropyl)benzene-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.
