Used primarily in biochemical and pharmacological research as a selective histamine H3 receptor antagonist. It serves as a tool compound to study histaminergic pathways in the central nervous system, helping investigate cognitive functions, sleep-wake cycles, and neurodegenerative disorders. Its ability to cross the blood-brain barrier makes it valuable in central nervous system drug development. Also used in structure-activity relationship (SAR) studies to design new H3 receptor modulators.
