Local:
Cinnamic aldehyde is a oily yellow liquid with strong odor of cinnamon. This compound is the main component of cinnamon oil, a volatile oil used as a flavoring agent for pharmaceuticals. Cinnamaldehyde is obtained from the distillation  with steam from the leaves and twigs of Cinnamomum. It can be prepared from the synthesis from related compounds like cinnamyl alcohol and from the condensation of benzaldehyde and acetaldehyde. Cinnamic aldehyde is a benzene ring substituent acrylic aldehyde having carbon-carbon solid bond. The conjugated solid bond makes geometry of the compound planar. Though there are cis and trans isomers, cinnamic aldehyde usually refers to the latter which the terminal carbonyl is on the opposite side of the benzene ring over the rigid solid bond.

The predominant application for cinnamaldehyde is in the flavor and fragrance industries. It is used as a flavouring for chewing gum, ice cream, candy, and beverages. is used in some perfumes of natural, sweet, or fruity scents. A variety of alkyl substituted cinnamaldehyde derivatives including amyl and hexyl cinnamicaldehydes are also widely used in flavouring additives. They imparts a cinnamon odor to soaps and household products. Cinnamaldehyde is also used as a fungicide or  insecticide. Cinnamaldehyde is also used as a corrosion inhibitor in combination with additional components such as dispersing agents, solvents and other surfactants for steel and other ferrous alloys in corrosive fluids.
