Chemical Structure
Description
1-(4-Chloro-2-methylphenyl)-3-(1-((4-fluorophenyl)sulfonyl)piperidin-4-yl)urea (C19H21ClFN3O3S) contains a steroid core, an amide group, a sulfone 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.
