Used in pharmaceutical research as a potent and selective antagonist for dopamine D3 receptors, this compound plays a key role in studying neurological disorders such as schizophrenia, drug addiction, and Parkinson’s disease. Its ability to cross the blood-brain barrier makes it valuable in developing treatments targeting central nervous system functions. It is also employed in structure-activity relationship (SAR) studies to design new neuroactive agents with improved selectivity and reduced side effects.
