Used in research as a potent and selective antagonist for serotonin receptors, particularly 5-HT2A, aiding in the study of neurological pathways related to mood, perception, and cognition. Commonly employed in pharmacological assays to investigate the role of serotonergic signaling in psychiatric disorders such as schizophrenia and depression. Also utilized in radiolabeled form for receptor binding studies and autoradiography to map receptor distribution in brain tissues. Its structural features make it a valuable scaffold in the development of novel psychoactive drugs and diagnostic tools in neuroscience.
