Ethyl levulinate is an organic compound with the formula CH<sub>3</sub>C(O)CH<sub>2</sub>CH<sub>2</sub>C(O)OC<sub>2</sub>H<sub>5</sub>. It is an ester derived from the keto acid levulinic acid. Ethyl levulinate can also be obtained by reaction between ethanol and furfuryl alcohol. These two synthesis options make ethyl levulinate a viable biofuel option, since both precursors can be obtained from biomass: levulinic acid from 6-carbon polymerized sugars such as cellulose, and furfural from 5-carbon polymerized sugars such as xylan and arabinan.
