Metabolite Identification
Common NameBenzofuran
DescriptionBenzofuran, also known as coumaron or 1-oxaindene, belongs to the class of organic compounds known as benzofurans. These are organic compounds containing a benzene ring fused to a furan. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Benzothiophene, an analog with a sulfur instead of the oxygen atom. Benzofuran is a drug. benzofuran has been detected, but not quantified, in several different foods, such as alcoholic beverages, coffee and coffee products, herbs and spices, root vegetables, and tea. This could make benzofuran a potential biomarker for the consumption of these foods. This colourless liquid is a component of coal tar. Benzofuran is the heterocyclic compound consisting of fused benzene and furan rings. Benzofuran is a potentially toxic compound. For example, psoralen is a benzofuran derivative that occurs in several plants. Isobenzofuran, the isomer with oxygen in the adjacent position.
