Levulinic acid, or 4-oxopentanoic acid, is an organic compound with the formula CH₃C(O)CH₂CH₂CO₂H. It is classified as a keto acid. This white crystalline solid is soluble in water and polar organic solvents. It is derived from degradation of cellulose and is a potential precursor to biofuels, such as ethyl levulinate.
