Used as a key intermediate in the synthesis of pharmaceuticals and bioactive compounds, particularly in the development of antidiabetic and anti-inflammatory agents. Its aldehyde and carboxylic acid functional groups allow for versatile chemical modifications, enabling the formation of Schiff bases, esters, and amides for drug design. Also employed in the preparation of fluorescent probes and sensors due to its ability to undergo condensation reactions that yield conjugated systems with light-emitting properties. Shows potential in materials science for constructing organic frameworks with optoelectronic applications.
