Chemical Structure
Description
CATO supplies 4-Methyl-6-phenyl-2H-thiazolo[3,2-a][1,3,5]triazine-2-thione (CAS 89012-16-8), a certified reference material (molecular formula C12H9N3S2, MW 259.35 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-Methyl-6-phenyl-2H-thiazolo[3,2-a][1,3,5]triazine-2-thione is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 259.35 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.
