Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of centrally acting agents such as cough suppressants and neuroactive drugs. Its structure supports the design of compounds targeting the central nervous system, including sigma receptor ligands and NMDA receptor modulators. Commonly employed in medicinal chemistry for constructing bioactive molecules due to its rigid, stereochemically defined scaffold. Also utilized in the preparation of enzyme inhibitors and receptor agonists/antagonists in research settings.
