Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Chlorophenyl)-4-methyl-4h-1,2,4-triazole.
CATO supplies 3-(4-Chlorophenyl)-4-methyl-4h-1,2,4-triazole (CAS 168968-40-9), a certified reference material (molecular formula C9H8ClN3, MW 193.63 g/mol) for analytical method development and quality control.
3-(4-Chlorophenyl)-4-methyl-4h-1,2,4-triazole (C9H8ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3-(4-Chlorophenyl)-4-methyl-4h-1,2,4-triazole 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.
