Used as a potent and selective antagonist for serotonin receptors, particularly 5-HT2A, in neuroscience research. Helps in studying psychiatric disorders such as schizophrenia and depression by modulating receptor activity. Also employed in radiolabeled form for receptor binding assays and imaging studies to map receptor distribution in brain tissues. Its high selectivity and affinity make it valuable in pharmacological profiling of novel psychoactive compounds.
