5-(4-Ethyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-4-methyl-2-phenylthiazole CAS 219860-31-8

Description

5-(4-Ethyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-4-methyl-2-phenylthiazole (CAS 219860-31-8), molecular formula C15H16N4S2 and molecular weight 316.44 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 5-(4-Ethyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-4-methyl-2-phenylthiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.44 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
