Chemical Structure
Description
6-(2-Chlorophenyl)-1-[(2,6-dichlorophenyl)methyl]-2-oxo-1,2-dihydropyridine-3-carbonitrile (C19H11Cl3N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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 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).
