Chemical Structure

2-Methylthieno[3,2-b]thiophene CAS 13393-75-4 chemical structure

Description

2-Methylthieno[3,2-b]thiophene (CAS 13393-75-4) is a high-purity analytical reference standard with the molecular formula C7H6S2 and a molecular weight of 154.25 g/mol.

The molecular framework of 2-Methylthieno[3,2-b]thiophene (C7H6S2) is characterized by sulfur-containing functionality, 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-Methylthieno[3,2-b]thiophene 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.
