Chemical Structure
Description
3-Bromo-4-((5-chloro-6-oxo-1-phenyl-1,6-dihydropyridazin-4-yl)oxy)-5-methoxybenzaldehyde (C18H12BrClN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
