Used primarily in scientific research for studying serotonin receptor activity, particularly as a selective antagonist for the 5-HT6 receptor subtype. This compound helps researchers investigate the role of 5-HT6 receptors in cognitive functions, memory, and neurodegenerative conditions such as Alzheimer's disease. Due to its selectivity, it is valuable in pharmacological assays and behavioral studies in preclinical models. It is not intended for human therapeutic use and is restricted to laboratory research.
