Chemical Information

FooDB Name

Fur-2-aldehyde

Description

Furfural, also known as 2-furaldehyde or 2-furyl-methanal, belongs to the class of organic compounds known as aryl-aldehydes. Aryl-aldehydes are compounds containing an aldehyde group directly attached to an aromatic ring. It is an aldehyde that is furan with the hydrogen at position 2 substituted by a formyl group. It is a colorless liquid, although commercial samples are often brown. It is a product of the dehydration of sugars, as occur in a variety of agricultural by-products, including corncobs, oat, wheat bran, and sawdust. Furfural was first isolated in 1821 by the German chemist Johann Wolfgang D√∂bereiner, who produced a small sample as a by-product of formic acid synthesis. Furfural dissolves readily in most polar organic solvents, but it is only slightly soluble in either water or alkanes.
