Chemical Structure
Description
1-[(3-Chlorophenyl)methyl]-3-[(2,6-dichlorophenyl)methyl]-2-methyl-1,4-dihydropyridin-4-one (C20H16Cl3NO) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
