Chemical Structure
Description
Ethyl 2-{2,4-dichloro-5-[3-(4-nitrophenoxy)thiophene-2-amido]phenoxy}acetate (C21H16Cl2N2O7S) contains a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
