Applications & Uses

Uses

5-(Chloromethyl)furfural is a lipid oxidation product derived from soybean phospholipids. It is a biofuel precursor in the co-processing of carbohydrates and lipids in oil crops for production of hybrid biodiesel.

General Description

5-(Chloromethyl) Furfural (CMF) is a potential chemical building block for replacing petroleum-derived chemicals derived from lignocellulosic feedstocks. It is gaining traction as a more practical alternative to 5-(hydroxymethyl)furfural (HMF).
