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 behavioral pharmacology studies due to its ability to differentiate D3 from D2 receptor activity. Investigated for its role in reducing drug-seeking behavior in preclinical models, making it a compound of interest in developing treatments for substance use disorders. Not approved for clinical use; strictly for experimental research.
