8-Hydroxyquinoline, or oxyquinoline, is an organic compound with the formula C9H7NO, a derivative of quinoline. It is usually extracted from coal tar.[1] This white compound is widely used as a chelating agent, where it binds to metals as a bidentate ligand. It is widely used commercially, although under a variety of names.[2][3]

It is used as a metal chelator, antiseptic, disinfectant and pesticide.[4][5] Its solution in alcohol are used as liquid bandages. It once was of interest as an anti-cancer drug.[6]

The roots of the invasive plant Centaurea diffusa release the 8-hydroxyquinoline, which has a negative effect on plants that have not co-evolved with it.
