chebi: A monocyclic heteroarene with a structure consisting of a 5-membered ring containing four carbons and one oxygen, with formula C<small><sub>4</sub></small>H<small><sub>4</sub></small>O. It is a toxic, flammable, low-boiling (31°C) colourless liquid.
chembl: FURAN is a small molecule listed in the ChEMBL database but has not progressed to an approved clinical phase.
wikipedia: 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.  Its odor is strong and chloroform-like.  It is toxic and may be carcinogenic in humans. Furan is used as a starting point for other speciality chemicals.
