2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-4-(3-(trifluoromethyl)phenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one CAS 343373-37-5 chemical structure

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-(trifluoromethyl)phenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one.

2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-4-(3-(trifluoromethyl)phenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 343373-37-5), molecular formula C15H7ClF6N4O and molecular weight 408.69 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H7ClF6N4O, 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-4-(3-(trifluoromethyl)phenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 408.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
