Chemical Structure

(2r,3r,4s)-2,3,4-Trihydroxy-4-(2-phenyl-2h-1,2,3-triazol-4-yl)butyl 4-methylbenzenesulfonate CAS 289697-84-3 chemical structure

Description

(2r,3r,4s)-2,3,4-Trihydroxy-4-(2-phenyl-2h-1,2,3-triazol-4-yl)butyl 4-methylbenzenesulfonate (C19H21N3O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
