Metabolite Identification

Common Name

2-Ethyl-5-methylfuran

Description

2-Ethyl-5-methylfuran, also known as furan, 2-methyl, 5-ethyl, 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-Ethyl-5-methylfuran is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on 2-Ethyl-5-methylfuran.
