| Common Name | 4-Methoxybenzaldehyde |
|---|
| Description | 4-Methoxybenzaldehyde, also known as 4-anisaldehyde or p-formylanisole, belongs to the class of organic compounds known as benzoyl derivatives, with the chemical formula CH3OC6H4CHO. These are organic compounds containing an acyl moiety of benzoic acid with the formula (C6H5CO-). Anisaldehyde is prepared commercially by oxidation of 4-methoxytoluene (p-cresyl methyl ether) using manganese dioxide to convert a methyl group to the aldehyde group. 4-Methoxybenzaldehyde is a sweet, almond, and anise tasting compound. 4-Methoxybenzaldehyde can be found, on average, in the highest concentration within a few different foods, such as cumins, star anises, and fennels. 4-Methoxybenzaldehyde has also been detected, but not quantified, in several different foods, such as cornmints, anises, herbs and spices, tarragons, and tea. The related ortho isomer has a scent of licorice. It is a colorless liquid with a strong aroma. 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. It is used as an intermediate in the synthesis of other compounds important in pharmaceuticals and perfumery. |
