Chemical Structure
Description
(3-Amino-4-((4-chlorophenyl)sulfonyl)-5-(o-tolylamino)thiophen-2-yl)(p-tolyl)methanone (C25H21ClN2O3S2) 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).
