This compound is primarily used in pharmacological research as a potent dopamine receptor antagonist, particularly targeting D2 receptors. It is valuable in studying the binding properties and functions of dopamine receptors in the brain, aiding in the understanding of neurological disorders such as schizophrenia and Parkinson's disease. Additionally, it serves as a tool in the development of antipsychotic drugs, helping to identify and test new therapeutic agents that target dopamine pathways. Its application extends to behavioral studies, where it is used to assess the role of dopamine in various cognitive and motor functions.
