General description

Methyl levulinate can be synthesized from glucose in the presence of a few drops of dilute sulfuric acid in methanol.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is considered environmentally benign and has been enhanced for "Safer Solvents and Auxiliaries". Click here for more information.

Application

Methyl levulinate can undergo Meerwein–Ponndorf–Verley (MPV) reduction in the presence of lewis acid zeolite like Hf-beta to give 4-hydroxypentanoates.
