Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its aldehyde and carboxylic acid functional groups allow for diverse derivatization, such as condensation reactions or cyclizations, enabling the construction of heterocyclic compounds. It is also employed in the development of fluorescent probes and sensors due to its ability to form conjugated systems. Additionally, it serves as a building block in the synthesis of bioactive molecules, including potential anti-inflammatory and antimicrobial agents.
