Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-4-(3-fluorophenyl)-5-methyl-2,4-dihydro-3H-1,2,4-triazol-3-one.
2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-4-(3-fluorophenyl)-5-methyl-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 860786-22-7) is a high-purity analytical reference standard with the molecular formula C15H9ClF4N4O and a molecular weight of 372.70 g/mol.
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)-4-(3-fluorophenyl)-5-methyl-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 372.70 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-4-(3-fluorophenyl)-5-methyl-2,4-dihydro-3H-1,2,4-triazol-3-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
