gamma-Valerolactone is an organic compound with the formula C5H8O2. This clear liquid is one of the more common lactones. It is a structural isomer of delta-valerolactone. Because of its herbal odor, it is used in the perfume and flavor industries.[2]

Potential applications

gamma-Valerolactone is a promising "green" liquid fuel. Levulinic acid, a derivative of glucose and other sugars, can be cyclized and the product hydrogenated to give gamma-valerolactone, and the product has potential applications as a liquid fuel.[3]
