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 prepared from catechol, beginning with ethylation to give guethol (1). This ether condenses with glyoxylic acid to give the corresponding mandelic acid derivative (2), which by oxidation (3) and decarboxylation, gives ethylvanillin (4).^[1]

Application

As a flavorant, ethylvanillin is about three times as potent as vanillin and is used in the production of chocolate.^[1]

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.^[2]
