Metabolite Identification
Common Name2-Ethylfuran
Description2-Ethylfuran, also known as alpha-ethylfuran or 2-ethyloxole, is a member of the class of furans that is furan in which the hydrogen atom at position 2 has been replaced by an ethyl group. It has a role as a plant metabolite, a fragrance, a Maillard reaction product and a bacterial metabolite. It is a member of furans and a volatile organic compound. It derives from a furan. 2-ethylfuran belongs to the class of organic compounds known as heteroaromatic compounds. Heteroaromatic compounds are compounds containing an aromatic ring where a carbon atom is linked to an hetero atom. 2-Ethylfuran is a sweet, burnt, and earthy tasting compound. 2-Ethylfuran is found, on average, in the highest concentration within kohlrabis. 2-Ethylfuran has also been detected, but not quantified, in several different foods such as cauliflowers, corns, cereals and cereal products, sweet bay, and sweet basils.
