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).〔Karl-Georg Fahlbusch, Franz-Josef Hammerschmidt, Johannes Panten, Wilhelm Pickenhagen, Dietmar Schatkowski, Kurt Bauer, Dorothea Garbe, Horst Surburg "Flavors and Fragrances" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim: 2002.
