Many derivatives of 8-hydroxyquinoline have been prepared and examined, some looking toward increased specificity as precipitating reagents, others toward an increase in the intensity of the color of the metal derivatives. Of the derivatives which have been studied, attention has been centered principally on the alkyl and halogen derivatives on the one hand and on the aromatic azo derivatives on the other. This paper deals with the preparation and properties of an 8-hydroxyquinoline bearing a second hydroxyl group, 5,8-dihydroxyquinoline. In this substance are combined the properties of chelate ring formation with metals and the oxidation-reduction behavior characteristic of the hydroquinones.
