Used in research as a potent and selective antagonist for dopamine D3 receptors, showing potential in the development of treatments for neurological disorders such as Parkinson’s disease, schizophrenia, and substance use disorders. Its structure allows for high affinity binding to D3 receptors with minimal activity at D2 receptors, reducing the risk of motor side effects. Investigated for its role in modulating reward pathways, making it a candidate for anti-addiction therapies. Also employed as a pharmacological tool in receptor binding assays and neurochemical studies to understand dopaminergic system function.
