Used in organic synthesis as a building block for creating more complex molecules, particularly in the development of pharmaceuticals and bioactive compounds. It serves as a precursor in the synthesis of heterocyclic compounds, which are essential in drug discovery and material science. Its formyl and carboxylic acid functional groups make it versatile for coupling reactions, enabling the production of diverse chemical structures. Additionally, it is employed in the design of organic electronic materials due to its conjugated system, which can enhance electron transport properties.
