Other names :
Cinnamal ; 3-phenylprop-2-enal ; Cassia aldehyde ; Benzylidene acetaldehyde ; Phenyl acrolein
Volatility :
Heart/Base
Uses in perfumery :
Cinnamaldehyde gives a spicy note to fruity and oriental accords.
Natural availability :
Cinnamaldehyde is present in a large quantity in Cassia EO (about 90%) and Ceylon Cinnamon EO (about 75%). It can therefore be extracted from these essential oils by fractional distillation.
Year of discovery :
Discovered en 1856.
Other comments :
Cinnamaldehyde is one of the 26 allergens in perfumery.
Price Range :
€
Stability :
Aldehydes may form diethylacetals in alcoholic perfumes, with no real impact on their smell

Synthesis route :
The synthesis of Cinnamaldehyde is made by a condensation of Benzaldehyde with Acetaldehyde, using an excess of Benzaldehyde and gradually adding Acetaldehyde, in order to avoid self-condensation of the latter.
Synthesis precursor :
Hydrogenation of Cinnamaldehyde provides DihydroCinnamaldehyde and DihydroCinnamyl Alcohol. Moreover, the oxidation of the aldehyde gives a Cinnamic Acid, another compound of olfactory interest. Finally, Cinnamaldehyde forms a Schiff base by reaction with Methyl Anthranilate or Indole for example.
Isomerism :
Like Cinnamyl Alcohol, Cinnamaldehyde can be divided into two diastereoisomers: trans or cis. Trans is the most found in nature. Both have a cinnamon-like smell, but the trans is warmer and smells even more like cinnamon than cis. The raw material used in perfumery is usually a mixture of the two isomers.
