Chemical Structure
Description
Methyl 2-phenyl-2-(3-{3-[3-(trifluoromethyl)phenyl]-1,2,4-oxadiazol-5-yl}propanamido)acetate (C21H18F3N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
