Used in scientific research to study the role of the 5-HT1A serotonin receptor in the central nervous system. It acts as a selective antagonist, helping researchers understand serotonin signaling pathways involved in mood, anxiety, and depression. Commonly applied in neuropharmacology studies using animal models to evaluate potential antidepressant and anxiolytic drug effects. Also utilized in receptor binding assays to assess affinity and selectivity for serotonin receptors.
