This article is about the heterocyclic chemical compound. For its purportedly recreational derivative drugs, see Benzofury (disambiguation).
Benzofuran is the heterocyclic compound consisting of fused benzene and furan rings. This colourless liquid is a component of coal tar. Benzofuran is the structural nucleus (parent compound) of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants.
