Used in research as a potent and selective antagonist for the 5-HT6 receptor, making it a valuable tool compound in neuroscience studies focused on cognitive function, memory, and neurodegenerative diseases such as Alzheimer's. It has shown potential in preclinical models to enhance learning and memory, supporting its investigation in the development of nootropic and antipsychotic agents. Due to its blood-brain barrier permeability and high affinity for 5-HT6 receptors, it is often employed in pharmacological assays to elucidate serotonin receptor pathways and evaluate behavioral responses in animal models.
