Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of biologically active compounds. Its aldehyde and ester functional groups allow for versatile chemical transformations, such as condensation reactions and nucleophilic additions, making it valuable in constructing heterocyclic systems. Commonly employed in the preparation of thiophene-based derivatives that exhibit potential antifungal, antibacterial, or anti-inflammatory properties. Also utilized in materials science for the synthesis of conjugated organic molecules used in organic electronics.
