Used primarily in neuroscience research, it acts as a selective agonist for the dopamine D4 receptor. It helps in studying the role of D4 receptors in various brain functions, including cognition, behavior, and potential links to psychiatric disorders like schizophrenia. Additionally, it is utilized in pharmacological studies to explore receptor signaling pathways and develop targeted therapies for neurological conditions. Its application also extends to understanding the mechanisms of dopamine-related reward systems and addiction.
