3-Formylbenzoic acid(CAT: R036690) is an aromatic compound featuring a benzene ring substituted with a formyl group at the meta (3-) position relative to a carboxylic acid. This dual-functionality structure offers versatile reactivity, with the aldehyde group suitable for condensation reactions such as Schiff base or imine formation, and the carboxylic acid moiety allowing for esterification, amidation, or salt formation. Commonly used as an intermediate in pharmaceutical, agrochemical, and material synthesis, 3-formylbenzoic acid serves as a building block for heterocyclic compounds and functionalized organic frameworks.
