2,4-Dimethoxybenzaldehyde（Cat No.:R009023）is an aromatic aldehyde featuring methoxy groups at the 2 and 4 positions of the benzene ring. This compound is widely used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, fragrances, and organic materials. The methoxy substituents enhance electron density on the ring, increasing reactivity in electrophilic aromatic substitution and condensation reactions, such as the formation of Schiff bases and chalcones. It typically appears as a pale yellow crystalline solid, soluble in organic solvents like ethanol and ether, and is stable under standard laboratory storage conditions.
