Aldehyde
Definition
An organic compound containing a carbonyl functional group bonded to a hydrogen atom (the formyl group, -CHO), necessarily located at the end of a carbon chain. Aldehydes are obtained industrially or in the laboratory through the dehydrogenation or controlled oxidation of primary alcohols and are widely used in chemical synthesis, the perfume industry, and disinfectant production.
