Used as a potent and selective antagonist of the 5-HT2A receptor in neuroscience research, particularly in studies related to serotonin signaling, hallucinogenic effects, and psychiatric disorders. It serves as a pharmacological tool to investigate the role of 5-HT2A receptors in behavioral models, including those for schizophrenia, depression, and anxiety. Its structural features allow for high affinity binding, making it valuable in receptor binding assays and functional studies. Due to its specificity, it is also employed in comparative studies with other serotonergic compounds to evaluate receptor subtype selectivity and downstream signaling pathways.
