Used in pharmaceutical research as a potent and selective antagonist for serotonin receptors, particularly 5-HT6, showing potential in the development of cognitive enhancers for neurodegenerative disorders such as Alzheimer's disease. Demonstrates good blood-brain barrier penetration and oral bioavailability in preclinical models, making it a valuable candidate in studies targeting memory impairment and neurobehavioral conditions. Also employed in structure-activity relationship (SAR) studies to optimize receptor binding affinity and selectivity in central nervous system drug discovery.
