Chemical Structure

3,3'-Dichloro-2,2'-bithiophene CAS 145386-39-6 chemical structure

Description

The occurrence of 3,3'-Dichloro-2,2'-bithiophene is closely related to sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,3'-Dichloro-2,2'-bithiophene (CAS 145386-39-6), molecular formula C8H4Cl2S2 and molecular weight 235.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,3'-Dichloro-2,2'-bithiophene (C8H4Cl2S2) 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. 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 3,3'-Dichloro-2,2'-bithiophene 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.
