Chemical Structure
Description
4-Chloro-N-(2-((2-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)amino)ethyl)amino)phenyl)benzenesulfonamide (C20H17Cl2F3N4O2S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
