Description
6,8-Dichlorochromone-3-carboxaldehyde 6,8-dichloro-4-oxo-4H-chromene-3-carbaldehyde 6,8-dichloro-4-oxochromene-3-carbaldehyde 64481-10-3 (C10H10Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
