Used in pharmaceutical research as a potent and selective antagonist of the histamine H3 receptor. It is investigated for its potential in treating neurological and cognitive disorders such as narcolepsy, attention deficit hyperactivity disorder (ADHD), and Alzheimer's disease due to its ability to modulate neurotransmitter release in the central nervous system. Shows good blood-brain barrier penetration, making it suitable for central targets. Also employed as a reference compound in receptor binding assays and pharmacokinetic studies.
