Used primarily in scientific research as a selective antagonist for serotonin receptors, particularly 5-HT2A and 5-HT2C subtypes. It serves as a pharmacological tool to study the role of these receptors in neurological pathways related to mood, perception, and cognition. Commonly employed in in vitro and in vivo studies to investigate the mechanisms of hallucinogens and antipsychotic drugs. Also utilized in radiolabeled form for receptor binding assays to map receptor distribution in brain tissue. Not intended for therapeutic use or human consumption.
