6-Chloro-3-(4-(trifluoromethyl)phenyl)-[1,2,4]triazolo[4,3-b]pyridazine (CAS 175204-95-2) is a high-purity analytical reference standard with the molecular formula C12H6ClF3N4 and a molecular weight of 298.65 g/mol.
6-Chloro-3-(4-(trifluoromethyl)phenyl)-[1,2,4]triazolo[4,3-b]pyridazine (C12H6ClF3N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
