Used in research settings as a selective antagonist for dopamine D3 receptors, aiding in the study of neurological pathways related to addiction, schizophrenia, and Parkinson’s disease. Shows potential in modulating reward-seeking behavior and improving cognitive function in preclinical models. Investigated for its role in reducing drug cravings, particularly in substance use disorders, due to its ability to cross the blood-brain barrier effectively. Currently limited to laboratory and experimental use, with no approved clinical applications as of now.
