4-Formyl-3-methoxybenzoic acid（Cat No.:L018285）is an aromatic carboxylic acid featuring a formyl group at the 4-position and a methoxy group at the 3-position on a benzoic acid ring. This multifunctional molecule combines electron-donating (methoxy) and electron-withdrawing (formyl and carboxyl) groups, giving it a unique electronic profile that enhances its versatility in organic synthesis. It serves as a valuable intermediate in the preparation of pharmaceuticals, dyes, and fine chemicals. The aldehyde group enables further derivatization via condensation, reduction, or oxidation reactions, making it a useful building block for complex aromatic and heterocyclic compounds.
