Used in pharmaceutical research as a potent and selective antagonist of the histamine H3 receptor. It is primarily investigated for its potential in treating neurological disorders such as narcolepsy, attention deficit hyperactivity disorder (ADHD), and other conditions involving excessive daytime sleepiness. Due to its ability to cross the blood-brain barrier and modulate neurotransmitter release, it serves as a valuable tool compound in studying histaminergic pathways. Also utilized in preclinical studies to evaluate cognitive enhancement and wake-promoting effects.
