Chemical Structure

1-methyl-4-sulfanylsulfonyl-benzene CAS 45936-43-4 chemical structure

Description

The molecular framework of 1-methyl-4-sulfanylsulfonyl-benzene (C7H8O2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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).

1-methyl-4-sulfanylsulfonyl-benzene (CAS 45936-43-4) is a high-purity analytical reference standard with the molecular formula C7H8O2S2 and a molecular weight of 188.27 g/mol.

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 1-methyl-4-sulfanylsulfonyl-benzene 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.
