2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-4-(3-(trifluoromethyl)phenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one CAS 861206-72-6

Description

The molecular framework of 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-4-(3-(trifluoromethyl)phenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (C16H9ClF6N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-4-(3-(trifluoromethyl)phenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 861206-72-6) is a high-purity analytical reference standard with the molecular formula C16H9ClF6N4O and a molecular weight of 422.71 g/mol.

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.

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.
