Chemical Structure
Description
3-[(2,6-Dichlorophenyl)methyl]-2-methyl-1-(1-phenylethyl)-1,4-dihydropyridin-4-one (C21H19Cl2NO) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
