Chemical Structure
Description
6-(4-Isopropylphenyl)-3-methyl-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazole (CAS 945369-42-6) is a high-purity analytical reference standard with the molecular formula C13H14N4S and a molecular weight of 258.34 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 6-(4-Isopropylphenyl)-3-methyl-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.34 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.
