Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules due to its rigid, fused ring system and functional handles for chemical modification. Commonly employed in research settings for designing compounds with potential neurological activity, including antidepressants and anticonvulsants. Also utilized in the preparation of chiral building blocks for asymmetric synthesis, enhancing the efficiency of producing enantiomerically pure drugs.
