CATO manufactures 1,2-Dihydro-2-(4-methylphenyl)-5-phenyl-3H-1,2,4-triazol-3-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.
CATO supplies 1,2-Dihydro-2-(4-methylphenyl)-5-phenyl-3H-1,2,4-triazol-3-one (CAS 118946-50-2), a certified reference material (molecular formula C15H14N3O, MW 252.29 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, 1,2-Dihydro-2-(4-methylphenyl)-5-phenyl-3H-1,2,4-triazol-3-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 252.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
