Ethylvanillin is the organic compound with the formula (C2H5O)(HO)C6H3CHO.
This colorless solid consists of a benzene ring with hydroxyl, ethoxy, andformyl
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” . This ether condenses
with glyoxylic acid to give the corresponding mandelic acid derivative , which via
oxidation and decarboxylation gives ethylvanillin .
