Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its rigid, bicyclic structure and defined stereochemistry make it valuable in medicinal chemistry for modulating the potency, selectivity, and metabolic stability of drug candidates. Commonly employed in the preparation of central nervous system (CNS) agents and enzyme inhibitors where stereochemistry plays a critical role in biological activity. Also utilized in asymmetric synthesis and as a ligand scaffold in catalysis.
