2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-4-phenyl-2,4-dihydro-3H-1,2,4-triazol-3-one CAS 860789-81-7

Description

2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-4-phenyl-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 860789-81-7), molecular formula C15H10ClF3N4O and molecular weight 354.71 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-4-phenyl-2,4-dihydro-3H-1,2,4-triazol-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-4-phenyl-2,4-dihydro-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.
