Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the development of neuroactive agents and central nervous system (CNS) drugs. Its rigid bicyclic structure and functional groups make it valuable for designing compounds with high selectivity and binding affinity to biological targets such as receptors and enzymes. Commonly employed in the preparation of potent antagonists or modulators for neurological disorders, including pain management and psychiatric conditions. Its hydroxyl and amine functionalities allow for easy derivatization, enabling incorporation into more complex drug molecules.
