Used in research settings as a selective antagonist for serotonin receptors, particularly 5-HT1B and 5-HT1D, aiding in the study of migraine mechanisms and neuropharmacology. It helps investigate the role of serotonin in vascular and neuronal pathways, supporting the development of targeted therapies for neurological and psychiatric disorders. Due to its specificity, it is valuable in receptor binding assays and functional studies in vitro and in vivo. Not intended for clinical use or human therapeutics.
