Used in organic synthesis as an intermediate for pharmaceuticals and functional materials. The aldehyde group allows for Schiff base formation or reduction to primary amines, while the amide group provides polarity and hydrogen bonding capability. Commonly employed in the development of bioactive molecules, including potential anticonvulsant and anti-inflammatory agents. Also utilized in the preparation of fluorescent probes and conjugated polymers due to its aromatic backbone and reactive functional groups. Suitable for solid-phase synthesis and linker applications in combinatorial chemistry.
