gamma-Valerolactone is an organic compound with the formula CH3CH(CH2)3CO2. This colourless liquid is one of the more common lactones. It is a structural isomer of gamma-butyrolactone. Because of its herbal odor, it is used in the perfume and flavor industries.[2]


Potential applications

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

Illicit uses

gamma-Valerolactone is sometimes abused as an analogue of GHB.[4]
