aldehyde

   Also found in: Dictionary/thesaurus, Medical, Acronyms, Encyclopedia, Wikipedia 0.01 sec.

aldehyde

Any of a group of organic chemical compounds prepared by oxidation of primary alcohols, so that both the OH (hydroxyl) group and the adjacent carbon lose a hydrogen to give an oxygen joined by a double bond to a carbon atom (the aldehyde group, with the formula CHO).

Higher aldehydes are commonly used in perfumes.

The name is made up from alcohol dehydrogenation – that is, alcohol from which hydrogen has been removed. Aldehydes are usually liquids and include methanal, ethanal, benzaldehyde, formaldehyde, and citral.
