Chemical Structure
Description
[(E)-2-[1-(3,5-Dichlorophenyl)-4-(4-methoxybenzoyl)-1H-1,2,3-triazol-5-yl]ethenyl]dimethylamine (C20H18Cl2N4O2) contains a steroid core, an amide 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).
