Used as a key intermediate in organic synthesis, particularly in the preparation of complex natural products and pharmaceuticals. Its spirocyclic structure and hydroxyl group allow for selective functionalization, making it valuable in constructing stereochemically defined molecules. Commonly employed in the synthesis of prostaglandins and other bioactive compounds where a rigid backbone is required. Also utilized in fragrance chemistry due to its stability and ability to mimic cyclic ether motifs found in natural aromas.
