Used primarily in pharmacological research as a selective antagonist for the 5-HT1A receptor subtype, this compound helps investigate serotonin receptor functions in the central nervous system. It is valuable in studies related to anxiety, depression, and neuropharmacology, allowing researchers to block specific serotonin receptors to observe behavioral and neurochemical effects. Due to its selectivity, it aids in distinguishing 5-HT1A-mediated responses from other serotonin receptor activities. It is not used clinically but serves as a tool compound in neuroscience research.
