Used in research as a potent and selective antagonist for serotonin receptors, particularly 5-HT2A, making it valuable in neuroscience studies related to mood, perception, and psychiatric disorders. It serves as a pharmacological tool to investigate the role of serotonergic signaling in behavioral models and is also employed in the development of novel CNS-active compounds. Its structural features support binding affinity and selectivity, enabling detailed structure-activity relationship (SAR) studies in medicinal chemistry.
