Isovanillin is a phenolic aldehyde, an organic compound and isomer of vanillin.[2] It is a selective inhibitor of aldehyde oxidase. It is not a substrate of that enzyme, and is metabolized by aldehyde dehydrogenase into isovanillic acid.[3] Isovanillin can be used as a precursor in the total synthesis of morphine.[4][5]
