Used in pharmaceutical synthesis as an intermediate for histamine H3 receptor antagonists, particularly in developing drugs targeting neurological disorders such as narcolepsy, ADHD, and cognitive impairments. Its structure supports binding affinity and selectivity toward H3 receptors, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in research to study histaminergic pathways and their role in sleep-wake cycles and neurotransmitter regulation.
