Description

Levulinic acid is a precursor for the synthesis of biofuels, such as ethyl levulinate.

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.

DryPowder; Liquid|Solid|yellow to brown liquid which may congeal; with mild caramellic odour

4-oxopentanoic acid is an oxopentanoic acid with the oxo group in the 4-position. It has a role as a plant metabolite. It is a straight-chain saturated fatty acid and an oxopentanoic acid. It is a conjugate acid of a 4-oxopentanoate.
