CATO supplies 3-(4-Chlorophenyl)-5-((2,4-dichlorobenzyl)thio)-4-(p-tolyl)-4H-1,2,4-triazole (CAS 443740-26-9), a certified reference material (molecular formula C22H16Cl3N3S, MW 460.81 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 3-(4-Chlorophenyl)-5-((2,4-dichlorobenzyl)thio)-4-(p-tolyl)-4H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 460.81 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.
