al·de·hyde A0185700 (ăl′də-hīd′)n. Any of a class of highly reactive organic chemical compounds obtained by oxidation of primary alcohols, characterized by the common group CHO, and used in the manufacture of resins, dyes, and organic acids.
[German Aldehyd, from New Latin al. dehyd., abbr. for alcohol dehydrogenātum, dehydrogenized alcohol.]aldehyde (ˈældɪˌhaɪd) n1. (Elements & Compounds) any organic compound containing the group -CHO. Aldehydes are oxidized to carboxylic acids and take part in many addition reactions2. (Chemistry) (modifier) consisting of, containing, or concerned with the group -CHO: aldehyde group or radical.

aldehyde [al´dĕ-hīd] an organic compound containing the aldehyde functional group (-CHO); that is, one with a carbonyl group (C=O) located at one end of the carbon chain.acetaldehyde.al·de·hyde (al'dĕ-hīd), A compound containing the radical -CH=O, reducible to an alcohol (CH2OH) and oxidizable to a carboxylic acid (COOH), for example, acetaldehyde.aldehyde An organic compound with a formyl group (R-CHO), which is double-bonded to an O2 (i.e., a carbonyl group, C=O), single-bonded to a hydrogen and single-bonded to another group (e.g., methane, benzene, hydrogen, etc.). The aldehydes in some essential oils contribute to their pleasant odoor, including vanillin, cilantro and cinnamaldehyde.
