This compound is primarily utilized in pharmacological research as a selective dopamine D1 receptor antagonist. It is often employed in studies to understand the role of dopamine D1 receptors in the central nervous system, particularly in behaviors like locomotion, cognition, and reward mechanisms. Researchers use it to investigate the effects of D1 receptor blockade in animal models, helping to elucidate the pathways and mechanisms underlying conditions such as Parkinson's disease, schizophrenia, and addiction. Additionally, it serves as a tool to explore the interaction between dopamine receptors and other neurotransmitter systems, contributing to the development of potential therapeutic agents targeting dopamine-related disorders.
