Chemical Structure
Description
(E)-{1-[2-(4-chlorophenyl)-4-methyl-1,3-thiazol-5-yl]ethylidene}amino N-(4-methylphenyl)carbamate (C20H18ClN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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.
