3-Chloro-2-({4-methyl-5-[2-(1H-1,2,4-triazol-1-yl)propan-2-yl]-4H-1,2,4-triazol-3-yl}sulfanyl)-5-(trifluoromethyl)pyridine (CAS 339026-48-1) is a high-purity analytical reference standard with the molecular formula C14H13ClF3N7S and a molecular weight of 403.81 g/mol.
Based on its molecular formula C14H13ClF3N7S, 3-Chloro-2-({4-methyl-5-[2-(1H-1,2,4-triazol-1-yl)propan-2-yl]-4H-1,2,4-triazol-3-yl}sulfanyl)-5-(trifluoromethyl)pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 403.81 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
