Chemical Structure

3,4-Dimethylthiophene CAS 632-15-5 chemical structure

Description

3,4-Dimethylthiophene (CAS 632-15-5), molecular formula C6H8S and molecular weight 112.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, 3,4-Dimethylthiophene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 3,4-Dimethylthiophene 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.
