Used primarily in organic synthesis as an intermediate for the production of various pharmaceuticals and fine chemicals. It serves as a key building block in the synthesis of complex molecules, particularly in the development of active pharmaceutical ingredients (APIs). Its formyl and ester groups make it valuable for further functionalization, enabling the creation of compounds with specific biological activities. Additionally, it is employed in the preparation of liquid crystals and advanced materials, where its structural properties contribute to the desired performance characteristics. Its role in cross-coupling reactions and as a precursor for polymer synthesis further highlights its versatility in industrial applications.
