Used primarily in pharmaceutical research as a key intermediate in the synthesis of sigma receptor ligands, particularly targeting the sigma-1 receptor subtype. These ligands are investigated for their potential in treating neurological and psychiatric disorders, including neuropathic pain, depression, and neurodegenerative diseases like Alzheimer's. The compound's rigid bicyclic structure provides high selectivity and binding affinity, making it valuable in developing central nervous system agents. It is also employed in structure-activity relationship (SAR) studies to optimize potency and pharmacokinetic properties of new drug candidates.
