Used in research as a potent and selective antagonist for the 5-HT6 receptor, showing potential in the development of cognitive enhancers and treatments for neurodegenerative disorders such as Alzheimer's disease. Demonstrates good brain penetration and oral bioavailability in preclinical models, making it a valuable tool compound for studying serotonin receptor function and evaluating therapeutic strategies targeting cognitive impairment. Also employed in pharmacological studies to investigate the role of 5-HT6 receptors in mood, anxiety, and feeding behavior.
