Used primarily in research settings to study the role of serotonin receptors in the central nervous system. It acts as a selective antagonist for the 5-HT1D receptor subtype, helping to understand its function in various physiological processes. Often utilized in neuropharmacology studies to investigate serotonin's involvement in mood regulation, anxiety, and migraine pathways. Its application extends to exploring potential therapeutic targets for disorders related to serotonin dysregulation.
