Description
CATO supplies 1-(4-Chlorophenyl)-N-(3,5-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (CAS 321431-31-6), a certified reference material (molecular formula C16H11Cl3N4O, MW 381.64 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(4-Chlorophenyl)-N-(3,5-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.64 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.
CATO manufactures 1-(4-Chlorophenyl)-N-(3,5-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
