Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen atom. Chemical compounds containing such rings are also referred to as furans.

Furan is a colorless, flammable, highly volatile liquid with a boiling point close to room temperature. It is soluble in common organic solvents, including alcohol, ether, and acetone, and is slightly soluble in water.[2] Its odor is "strong, ethereal; chloroform-like".[3] It is toxic and may be carcinogenic in humans. Furan is used as a starting point for other speciality chemicals.[4]
