Description
CATO supplies 1-[(4-Chlorophenyl)methyl]-4-(4-methoxyphenyl)-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one (CAS 861206-11-3), a certified reference material (molecular formula C17H16ClN3O2, MW 329.78 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-[(4-Chlorophenyl)methyl]-4-(4-methoxyphenyl)-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.78 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)methyl]-4-(4-methoxyphenyl)-3-methyl-4,5-dihydro-1H-1,2,4-triazol-5-one 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.
