14Methoxybenzaldehyde

14-Methoxybenzaldehyde is an organic compound with the chemical formula C8H8O2. It is a derivative of benzaldehyde, with a methoxy group (-OCH3) substituted at the 14th position on the benzene ring. This compound is a colorless to slightly yellow liquid with a characteristic aromatic odor.

14-Methoxybenzaldehyde is used primarily as an intermediate in the synthesis of other chemical compounds. It is not typically used on its own due to its instability and reactivity. The methoxy group can be easily oxidized, leading to the formation of 14-methoxybenzoic acid, and the aldehyde group can undergo various reactions such as condensation, addition, and oxidation.

The compound can be synthesized through the reaction of 14-methoxybenzene with a suitable oxidizing agent, such as potassium dichromate (K2Cr2O7) in the presence of sulfuric acid (H2SO4). The reaction proceeds via the formation of a chromic acid ester, which then decomposes to yield 14-methoxybenzaldehyde.

14-Methoxybenzaldehyde is slightly soluble in water but soluble in most organic solvents such as ethanol, ethyl acetate, and dichloromethane. It is stable under normal temperatures but can decompose upon heating or exposure to strong oxidizing agents.

Safety precautions should be taken when handling 14-methoxybenzaldehyde due to its reactivity and potential to cause skin and eye irritation. It should be stored in a cool, well-ventilated area away from incompatible substances such as strong oxidizing agents.
