Description
As a certified reference material (CRM), 5-Amino-2-methylthiazole-4-carbonitrile 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.
5-Amino-2-methylthiazole-4-carbonitrile (CAS 31785-16-7) is a high-purity analytical reference standard with the molecular formula C5H5N3S and a molecular weight of 139.18 g/mol.
Owing to a nitrile group, sulfur-containing functionality, 5-Amino-2-methylthiazole-4-carbonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.18 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
