Chemical Structure

2,7-Dimethyl-1-benzothiophene-3-sulfonyl chloride CAS 1384431-09-7 chemical structure

Description

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.

2,7-Dimethyl-1-benzothiophene-3-sulfonyl chloride (CAS 1384431-09-7) is a high-purity analytical reference standard with the molecular formula C10H9ClO2S2 and a molecular weight of 260.76 g/mol.

The molecular framework of 2,7-Dimethyl-1-benzothiophene-3-sulfonyl chloride (C10H9ClO2S2) 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 its high hydrophobicity (logP), 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 2,7-Dimethyl-1-benzothiophene-3-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.
