Ethyl cinnamate is the ester of cinnamic acid and ethanol. It is present in the essential oil of cinnamon.[citation needed] Pure ethyl cinnamate has a "fruity and balsamic odor, reminiscent of cinnamon with an amber note".[1]

The p-methoxy derivative is reported to be a monoamine oxidase inhibitor.[2] It can be synthesized by the esterification reaction involving ethanol and cinnamic acid in the presence of sulfuric acid.
