Aldehyde

Organic compound containing the functional group R–CH=O

Aldehyde

In organic chemistry, an aldehyde (lat. alcohol dehydrogenatum, dehydrogenated alcohol) is an organic compound containing a functional group with the structure R−CH=O. The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are a common motif in many chemicals important in technology and biology.
