Used in research as a potent and selective antagonist for the sigma-2 receptor, this compound is valuable in neuroscience and oncology studies. It helps investigate cellular pathways linked to neurodegenerative diseases and cancer progression. Due to its high affinity for sigma-2 receptors, it is employed in receptor binding assays and imaging studies to understand receptor distribution and function in tissues. Its structure supports the development of novel therapeutic agents targeting receptor-mediated apoptosis in tumor cells. Also used as a reference compound in pharmacokinetic and metabolic stability tests during drug discovery.
