Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs. Its rigid bicyclic structure makes it valuable in medicinal chemistry for enhancing selectivity and binding affinity in drug candidates. Commonly employed in the preparation of inhibitors targeting enzymes such as phosphodiesterases (PDEs) and in the design of receptor modulators. Also utilized in research settings for scaffold development in heterocyclic chemistry due to its stability and stereochemical properties.
