Used as a research compound in pharmacological studies, particularly in the development of treatments targeting central nervous system disorders. It acts as a selective antagonist for specific neurotransmitter receptors, making it valuable in studying neurological pathways related to anxiety, depression, and cognitive function. Due to its ability to cross the blood-brain barrier, it is employed in preclinical models to evaluate receptor involvement in behavior and brain activity. Its hydrochloride salt form enhances solubility and stability, facilitating use in in vitro and in vivo experiments.
