8-Hydroxyquinoline

8-Hydroxyquinoline, or oxyquinoline, is an organic compound with the formula C9H7NO, a derivative of quinoline. It is usually extracted from coal tar. 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.

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

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.
