Used in research settings as a selective agonist for dopamine D3 receptors, aiding in the study of neurological pathways related to addiction, schizophrenia, and Parkinson’s disease. Shows potential in developing targeted therapies due to its high affinity for D3 over D2 receptors, reducing likelihood of side effects in central nervous system treatments. Also utilized in radiolabeled form for receptor binding assays and neuroimaging studies.
