Chemical Structure

5-Methylthiophene-2-thiol CAS 3970-28-3 chemical structure

Description

Structurally, 5-Methylthiophene-2-thiol (C5H6S2) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 130.23 g/mol, it falls into the low-molecular-weight range. 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).

5-Methylthiophene-2-thiol (CAS 3970-28-3), molecular formula C5H6S2 and molecular weight 130.23 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5-Methylthiophene-2-thiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
