Chemical Structure
Description
(5E)-5-[(2-{[(4-chlorophenyl)methyl]sulfanyl}-5-nitrophenyl)methylidene]-3-ethyl-2-sulfanylidene-1,3-thiazolidin-4-one (C19H15ClN2O3S3) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
