Chemical Structure
Description
Ethyl 3-(4-(2-((2-bromo-4-methylphenyl)amino)-2-oxoethoxy)-3-ethoxyphenyl)-2-cyanoacrylate (C23H23BrN2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine 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).
Ethyl 3-(4-(2-((2-bromo-4-methylphenyl)amino)-2-oxoethoxy)-3-ethoxyphenyl)-2-cyanoacrylate (CAS 333766-63-5), molecular formula C23H23BrN2O5 and molecular weight 487.34 g/mol, is a CATO reference standard with documented purity and traceability.
