3-Methylthiophene-2-thiol CAS 3970-30-7

Description

Compared with other compounds in its class, the molecular weight of 130.23 g/mol gives 3-Methylthiophene-2-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Methylthiophene-2-thiol (CAS 3970-30-7) is a high-purity analytical reference standard with the molecular formula C5H6S2 and a molecular weight of 130.23 g/mol.

Owing to sulfur-containing functionality, 3-Methylthiophene-2-thiol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.23 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-Methylthiophene-2-thiol 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.
