Used primarily as a reactive intermediate in organic synthesis, this compound serves as a building block for the preparation of complex molecules in pharmaceutical and agrochemical industries. Its spirocyclic structure and unsaturated lactone functionality make it valuable in ring-opening and cycloaddition reactions, enabling the construction of polycyclic frameworks. It is also employed in the development of biodegradable polymers due to its ability to undergo controlled polymerization, yielding materials with tailored degradation profiles. Additionally, it finds use in fragrance chemistry, where its structural features contribute to the stability and release characteristics of scent molecules.
