Butyl levulinate

What is Butyl levulinate?

Butyl levulinate has a sweet and slightly pungent caramellic odor with fruity undertones; mild sweet caramellicherbaceous taste; bitter taste.

Butyl levulinate was used in the synthesis of γ-valerolactone.

Butyl 4-Oxopentanoate is used in preparation and application of magnetic nano-solid acid catalyst iron oxide-polydopamine-sulfonic acid

Butyl levulinate is a derivative chemical of levulinic acid, from agricultural residue (rice straw)
