Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Methylthiophene-3-thiol (CAS 2527-76-6) 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, 2-Methylthiophene-3-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).
As a certified reference material (CRM), 2-Methylthiophene-3-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.
