Used primarily in scientific research as a potent and selective antagonist for dopamine D3 receptors. It serves as a valuable tool compound in neuropharmacology studies, helping researchers differentiate D3 receptor activity from D2 receptor effects in the central nervous system. Commonly employed in behavioral assays and receptor binding experiments to investigate the role of dopamine signaling in conditions such as addiction, schizophrenia, and Parkinson’s disease. Due to its high selectivity and blood-brain barrier permeability, it is frequently used in in vivo models to modulate dopaminergic pathways and assess potential therapeutic targets. Not intended for clinical use or human consumption.
