Chemical Structure
Description
4-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-chlorophenyl)butanoic acid (C25H22ClNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
