Used in pharmaceutical research as a key intermediate in the synthesis of central nervous system agents, particularly in the development of selective receptor modulators targeting neurological disorders such as anxiety, depression, and epilepsy. Its rigid polycyclic structure enhances binding affinity and selectivity for certain neurotransmitter receptors. Also explored in the design of novel analgesics due to its ability to interact with opioid and monoaminergic pathways. Limited use outside research settings due to ongoing preclinical evaluation.
