Chemical Structure
Description
6-(4-Chlorophenyl)-4-(2,3-dichlorophenyl)-2-(4-methylbenzyl)-4,5-dihydropyridazin-3(2H)-one (C24H19Cl3N2O) 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.
