Used in pharmaceutical research as a key intermediate in the synthesis of potent sigma receptor ligands. These compounds are investigated for their potential in treating neurological disorders such as schizophrenia, depression, and neuropathic pain. Its unique polycyclic structure enables high selectivity and binding affinity to sigma-1 and sigma-2 receptors, making it valuable in developing central nervous system therapeutics. Also explored in positron emission tomography (PET) tracer development due to its ability to cross the blood-brain barrier and target specific brain receptors.
