Chemical Information
FooDB Name2-Ethylfuran
Description2-Ethylfuran, also known as alpha-ethylfuran or 2-ethyloxole, 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 an extremely weak basic (essentially neutral) compound (based on its pKa). 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 garden tomato (var.), sweet cherries, corns, spearmints, and nuts. This could make 2-ethylfuran a potential biomarker for the consumption of these foods.
