Dimethoxybenzaldehyde

Dimethoxybenzaldehyde is an organic compound that belongs to the class of benzaldehydes. It is a colorless liquid with a pleasant, aromatic odor. The compound is used in the synthesis of other organic compounds, including pharmaceuticals and dyes.

Chemical Structure and Properties

Dimethoxybenzaldehyde, also known as veratraldehyde, has the chemical formula C9H10O3. It consists of a benzene ring substituted with two methoxy groups and one aldehyde group. The methoxy groups are electron-donating, which makes the compound more reactive than benzaldehyde.

The compound is soluble in common organic solvents, but only slightly soluble in water. It has a boiling point of 281°C and a melting point of 43°C.

Synthesis

Dimethoxybenzaldehyde can be synthesized by the Friedel-Crafts alkylation of vanillin with dimethyl sulfate. The reaction is catalyzed by aluminum chloride.

Applications

Dimethoxybenzaldehyde is used as a starting material in the synthesis of various organic compounds. It is used in the production of pharmaceuticals, dyes, and fragrances. It is also used as a flavoring agent in food and beverages.

Safety

Dimethoxybenzaldehyde is not classified as a hazardous substance. However, it can cause irritation to the eyes, skin, and respiratory tract. It is recommended to handle the compound with appropriate protective equipment.
