3-((E)-(3-acetylphenyl)diazenyl)-6-((E)-(4-chloro-2-phosphonophenyl)diazenyl)-4,5-dihydroxynaphthalene-2,7-disulfonic acid (C24H18ClN4O12PS2) contains a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine 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).
