Used in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals due to its reactive aldehyde and vinyl functional groups. It serves as a building block in cross-coupling reactions and polymer chemistry, enabling the development of specialty monomers and functional polymers. Also employed in fragrance and flavor synthesis, where it contributes to aromatic aldehyde profiles in perfumery. Its dual reactivity allows for use in cyclization reactions to form heterocyclic compounds important in medicinal chemistry.
