Used primarily in research settings as a potent antagonist for serotonin receptors, particularly the 5-HT2A and 5-HT2C subtypes. Its high affinity for these receptors makes it valuable in studies examining the role of serotonergic signaling in mood regulation, perception, and neurobehavioral disorders. It has been employed in radiolabeled form to map receptor distribution in brain tissues, aiding in the development of psychiatric medications. Due to its structural specificity, it also serves as a reference compound in pharmacological assays assessing receptor binding and functional activity. Not intended for therapeutic use.
