Furfural is an organic compound derived from a variety of agricultural byproducts, including corncobs, oat, wheat bran, and sawdust. The name furfural comes from the Latin word furfur, meaning bran, referring to its usual source.
Furfural is a heterocyclic aldehyde, with the ring structure shown at right. Its chemical formula is OC4H3CHO. It is a colorless oily liquid with the odor of almonds, which quickly darkens when exposed to air.
It is one of the components found in vanilla.

Furfural and related compounds are useful precursors and starting materials for industrial chemicals for use as pharmaceuticals, herbicides, stabilizers, and polymers. The current furfural manufacturing process utilizes biomass such as corn cob, sugar cane bagasse, switchgrass or wood waste as a raw material feedstock for obtaining glucose, glucose oligomers, cellulose, xylose, xylose oligomers, arabinose, hemicellulose, and other C5 and C6 sugar monomers, dimers, oligomers, and polymers. The hemicellulose and cellulose are hydrolyzed under acidic conditions to their constituent sugars, such as glucose, xylose, mannose, galactose, rhamnose, and arabinose. Xylose, which is a pentose (i.e., a C5 monosaccharide) is the sugar present in the largest amount in hemicellulose. In a similar aqueous acidic environment, the C5 sugars are subsequently dehydrated and cyclized to furfural. Under similar conditions, C6 sugars can be hydrolyzed and converted in low yields to furfural.
