4-Anisaldehyde (p-anisaldehyde, anisic aldehyde, or anise aldehyde) is an organic compound that is commonly encountered in fragrances, both synthetic and natural. The compound consists of a benzene ring with an aldehyde and a methoxy group. It is a clear liquid with a strong aroma. Two related isomers, ortho-anisaldehyde and meta-anisaldehyde, are also known but less commonly encountered. It provides sweet, floral and strong aniseed odor.

Production

Anisaldehyde is prepared commercially by oxidation of methoxytoluene (p-cresyl methyl ether) using manganese dioxide. It can also be produced by oxidation of anethole, a related fragrance that is found in some alcoholic beverages.^[3]

Uses

Being structurally related to vanillin, anisaldehyde is a widely used in the fragrance and flavor industry.^[3] Anisaldehyde is used as an intermediate in the synthesis of other compounds important in pharmaceuticals and perfumery. ortho-Anisaldehyde has a scent of licorice.

A solution of para-anisaldehyde in acid and ethanol is a useful stain in thin layer chromatography.^[4] Different chemical compounds on the plate can give different colors, allowing easy distinction.
