Ethylvanillin is the organic compound with the formula (C₂H₅O)(HO)C₆H₃CHO. This colorless solid consists of a benzene ring with hydroxyl, ethoxy, and formyl groups on the 4, 3, and 1 positions, respectively.

Preparation

Ethylvanillin is a synthetic molecule, not found in nature. It is prepared via several steps from catechol, beginning with ethylation to give "guethol" (1). This ether condenses with glyoxylic acid to give the corresponding mandelic acid derivative (2), which via oxidation (3) and decarboxylation gives ethylvanillin (4).

Application

As a flavorant, ethylvanillin is about three times as potent as vanillin and is used in the production of chocolate.

The molecule revolutionized both the design and aesthetics of olfactory art; artist Aimé Guerlain used it in "Jicky" (1889), one of the earliest uses of the synthetic molecules that freed scent artists from the limits of natural materials.
