Chemical Structure

2,4-Dichloro-6-methylbenzenesulphonyl chloride CAS 175278-26-9 chemical structure

Description

The occurrence of 2,4-Dichloro-6-methylbenzenesulphonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,4-Dichloro-6-methylbenzenesulphonyl chloride (CAS 175278-26-9), molecular formula C7H5Cl3O2S and molecular weight 259.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,4-Dichloro-6-methylbenzenesulphonyl chloride (C7H5Cl3O2S) 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2,4-Dichloro-6-methylbenzenesulphonyl 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.
