2-(6-chloro-3-pyridinyl)-1-hexyl-5-(trifluoromethyl)-1H-1,3-benzimidazole 400074-13-7 KS-00002XL3 (CAS 400074-13-7) is a high-purity analytical reference standard with the molecular formula C19H19ClF3N3 and a molecular weight of 381.82 g/mol.
2-(6-chloro-3-pyridinyl)-1-hexyl-5-(trifluoromethyl)-1H-1,3-benzimidazole 400074-13-7 KS-00002XL3 (C19H19ClF3N3) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
