Chemical Structure
Description
(2,4-Dichlorophenyl)(5-(5-((4-fluorophenoxy)methyl)-1,3,4-oxadiazol-2-yl)-1-methyl-1H-pyrrol-3-yl)methanone (C21H14Cl2FN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
