Chemical Structure
Description
(Z)-[2-(Benzenesulfonyl)-1-[2-(4-chlorophenyl)-4-methyl-1,3-thiazol-5-yl]ethylidene][(4-chlorophenyl)methoxy]amine (C25H20Cl2N2O3S2) 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.
