Chemical Structure

3,5-Dichlorothiophenol CAS 17231-94-6 chemical structure

Description

The molecular framework of 3,5-Dichlorothiophenol (C6H4Cl2S) is characterized by sulfur-containing functionality, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

3,5-Dichlorothiophenol (CAS 17231-94-6) is a high-purity analytical reference standard with the molecular formula C6H4Cl2S and a molecular weight of 179.07 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 3,5-Dichlorothiophenol 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.
