Used in organic synthesis as a key intermediate for the development of pharmaceuticals and bioactive compounds. It is particularly valuable in the synthesis of molecules with potential anticancer and antiviral properties. The aldehyde group allows for further functionalization, making it a versatile building block in medicinal chemistry. Additionally, it is employed in the creation of fluorescent probes and materials for optoelectronic applications due to its conjugated structure. Its incorporation into polymers and small molecules enhances their electronic properties, making it useful in materials science.
