Used in organic synthesis as a building block for complex heterocyclic compounds, particularly in the development of bioactive molecules. Its spirocyclic structure and furan ring make it valuable in medicinal chemistry for designing potential pharmaceutical intermediates. It also serves as a precursor in the synthesis of functional materials, including photoactive or electroactive compounds due to its conjugated system and oxygen-containing heterocycles. Its unique geometry supports research in stereoselective reactions and catalyst development.
