Also known as cinnamic aldehyde, 3-phenylacrylaldehyde, (E)-Cinnamic aldehyde, (E)-3-Phenyl-2-propenal, trans-Cinnamic aldehyde, (E)-3-Phenylpropenal, 3-Phenylacrolein

Cinnamaldehyde is an organic compound with the formula or . Occurring naturally as predominantly the trans (E) isomer, it gives cinnamon its flavor and odor. It is a phenylpropanoid that is naturally synthesized by the shikimate pathway. This pale yellow, viscous liquid occurs in the bark of cinnamon trees and other species of the genus Cinnamomum. It is an found in high concentrations in cinanamon essential oil.

Cinnamaldehyde is an organic compound with the formula or . Occurring naturally as predominantly the trans (E) isomer, it gives cinnamon its flavor and odor. It is a phenylpropanoid that is naturally synthesized by the shikimate pathway. This pale yellow, viscous liquid occurs in the bark of cinnamon trees and other species of the genus Cinnamomum. It is an found in high concentrations in cinanamon essential oil.

==Structure and synthesis== Cinnamaldehyde was isolated from cinnamon essential oil in 1834 by Jean-Baptiste Dumas and Eugène-Melchior Péligot and synthesized in the laboratory by the Italian chemist Luigi Chiozza in 1854. Synonyms for Cinnamaldehyde include 3-Phenyl-2-propenal, Cinnamic aldehyde, trans-Cinnamaldehyde, Cinnamal, Cinnamyl aldehyde, Cassia aldehyde, 3-Phenylacrolein, and β-Phenylacrolein.
