4-Anisaldehyde (also: p-anisaldehyde, anisic aldehyde, anise aldehyde) is an organic compound that is commonly encountered in the 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 almond odor. Atul Ltd, India is the largest manufacturer of Anisaldehyde in the world.
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.
Being structurally related to vanillin, anisaldehyde is a widely used in the fragrance and flavor industry. 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. Different chemical compounds on the plate can give different colors, allowing easy distinction.
