2-(4-Fluorophenyl)-6-(1H-indol-1-yl)imidazo[1,2-a]pyridine (CAS 573979-75-6), molecular formula C21H14FN3 and molecular weight 327.35 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Fluorophenyl)-6-(1H-indol-1-yl)imidazo[1,2-a]pyridine (C21H14FN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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.
