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.
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).
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.
