Chemical Structure
Description
3-((3-Chloro-4-fluorophenyl)sulfonyl)-7-hydroxy-2H-chromen-2-one (C15H8ClFO5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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.
