8-Hydroxyquinoline Application
8-Hydroxyquinoline is used as an intermediate for pharmaceuticals and agrochemicals. It is alos as a precipitating agent or chelating agent to separate metals. It is used in formulating anti-dandruff agents for shampoo.
8-Hydroxyqui oline is a monoprotic bidentate chelating agent, exhibits antiseptic, disinfectant, and pesticide properties, functioning as a transcription inhibitor.
8-Hydroxyquin oline (also known as oxine) is a chelating agent which has been used for the quantitative determination of metal ions.
In aqueous solution 8-hydroxyquin oline has a pKa value of ca. It reacts with metal ions, losing the proton and forming 8-hydroxyquinolinato-chelate complexes.
The aluminium complex is a common component of organic light-emitting diodes (OLEDs). Variations in the substituents on the quino line rings affect its luminescence properties.
In the photochemically induced excited-state zwitterionic isomers are formed in which the hydrogen atom is transferred from oxygen to nitrogen.
The complexes as well as the heterocycle itself exhibit antiseptic, disinfectant, and pesticide properties, functioning as a transcription inhibitor. Its solution in alcohol is used in liquid bandages. It once was of interest as an anti-cancer drug.
