Used as a potent and selective antagonist for the 5-HT2C receptor in neuroscience research, particularly in studies related to mood disorders, appetite regulation, and substance abuse. Its high selectivity allows for precise modulation of serotonin pathways without significant off-target effects on related receptors like 5-HT2A or 5-HT2B. Commonly employed in preclinical models to investigate the role of 5-HT2C in anxiety, depression, and obesity. Also utilized in radiolabeled form for receptor binding assays and neuroimaging studies to map receptor distribution and density in the brain.
