3-Methylbenzaldehyde, also known as m-tolualdehyde, is an organic compound with the chemical formula C8H8O. It is a derivative of benzaldehyde, with a methyl group attached to the meta position of the benzene ring. At room temperature, it typically exists as a colorless to pale yellow liquid with a characteristic almond-like odor. Its molecular weight is approximately 120.15 grams per mole. The compound has a boiling point around 199-201 degrees Celsius and a melting point around -5 degrees Celsius. It is sparingly soluble in water but readily soluble in many organic solvents such as ethanol and ether.

3-Methylbenzaldehyde is an aromatic aldehyde and participates in typical reactions of this functional group. It can undergo oxidation to form 3-methylbenzoic acid and reduction to form 3-methylbenzyl alcohol. It can also participate in condensation reactions, such as aldol condensations, and can be used in the synthesis of various organic molecules. Industrially, it is produced through the oxidation of m-xylene. It finds applications as an intermediate in the synthesis of dyes, pharmaceuticals, and fragrances. Its presence in certain natural products has also been noted.
