Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules with spirocyclic frameworks. Its rigid spiro structure contributes to enhanced metabolic stability and target selectivity in drug design. Commonly employed in the preparation of antiviral and anti-inflammatory agents. Also utilized in the fragrance industry due to its ability to impart long-lasting, musk-like olfactory characteristics. Serves as a building block in organic synthesis for constructing complex cyclic systems through ring-opening or functionalization reactions.
