Chemical Structure
Description
5-[2-[4-Chloro-2-(Trifluoromethyl)Phenyl]Hydrazinyl]-6-Imino-4-Oxonaphthalene-2-Sulfonic Acid (C17H11ClF3N3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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).
5-[2-[4-Chloro-2-(Trifluoromethyl)Phenyl]Hydrazinyl]-6-Imino-4-Oxonaphthalene-2-Sulfonic Acid (CAS 3836-78-0) is a high-purity analytical reference standard with the molecular formula C17H11ClF3N3O4S and a molecular weight of 445.80 g/mol.
