Chemical Structure
Description
2,5-Dichloro-N-[5,6-dimethyl-1-(propan-2-yl)-1H-1,3-benzodiazol-4-yl]benzene-1-sulfonamide (C18H19Cl2N3O2S) 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).
