Use

p-Anisaldehyde occurs in many essential oils, often together with anethole. It is a colorless to slightly yellowish liquid with a sweet, mimosa, hawthorn odor. p-Anisaldehyde can be hydrogenated to anise alcohol and readily oxidizes to anisic acid when exposed to air. Synthetic routes to anisaldehyde start from p-cresyl methyl ether, which is oxidized, for example, by manganese dioxide or by oxygen or peroxy compounds in the presence of transition metal catalysts .Another industrial process uses electrochemical oxidation in the presence of lower aliphatic alcohols via the corresponding anisaldehyde dialkyl acetal . Anisaldehyde may also be produced by methylation of 4-hydroxybenzaldehyde, which is easily obtained by oxidation of p-cresol or by Vilsmeier formylation of anisol.
