Metabolite Identification
Common Name5-Ethoxy-4,5-dihydro-2(3H)furanone
Description5-Ethoxy-4,5-dihydro-2(3H)furanone, also known as 4-ethoxy-4-hydroxybutyric acid g-lactone or 4-ethoxy-g-butyrolactone, belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. 5-Ethoxy-4,5-dihydro-2(3H)furanone 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 very few articles have been published on 5-Ethoxy-4,5-dihydro-2(3H)furanone.
