Cinnamaldehyde is used in agriculture because of its low toxicity, but it is a skin irritant. [25] Cinnamaldehyde may cause allergic contact stomatitis in sensitised individuals, however allergy to the compound is believed to be uncommon. [26] Cinnamaldehyde can contain traces of styrene, which arises during storage or transport. Styrene ...
Cinnamyl alcohol has a distinctive odor described as "sweet, balsam, hyacinth, spicy, green, powdery, cinnamic" and is used in perfumery [4] and as a deodorant. Cinnamyl alcohol is the starting material used in the synthesis of reboxetine .

Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] 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.
The commercial material often contains low levels of 2,6-di-tert-butyl-4-methoxyphenol as a stabilizer. It is a derivative of cinnamaldehyde with a hexyl substituent. One supplier reported that its hexyl cinnamaldehyde (or "hexyl cinnamic aldehyde") contained at least 90% trans isomer. [2]
Since acetaldehyde has an unfavourable deactivating effect on the lipase used in the synthesis, ethyl acetate can be used as reactant instead of vinyl acetate. In this transesterification reaction cinnamyl alcohol 1 reacts with ethyl acetate to form cinnamyl acetate 2 and ethanol. This synthesis requires the lipase Novozym 435, and is performed ...
In enzymology, a cinnamyl-alcohol dehydrogenase (EC 1.1.1.195) is an enzyme that catalyzes the chemical reaction. cinnamyl alcohol + NADP + cinnamaldehyde + NADPH + H +. Thus, the two substrates of this enzyme are cinnamyl alcohol and NADP +, whereas its 3 products are cinnamaldehyde, NADPH, and H +.
Nitration of cinnamaldehyde via acidification of a nitrate salt with H 2 SO 4 also yields the ortho-nitro compound, however it also yields some of the para-nitro compound, which is generally undesired. 2-Nitrocinnamaldehyde can also be prepared by reacting 2-nitrobenzaldehyde with acetaldehyde in a condensation reaction.
