Used in the synthesis of histamine H3 receptor antagonists, which are investigated for neurological disorders such as Alzheimer's disease, attention deficit hyperactivity disorder (ADHD), and epilepsy. It serves as a key intermediate in developing compounds that modulate neurotransmitter release in the central nervous system. Its structure allows for selective binding to histamine receptors, making it valuable in medicinal chemistry for designing drugs targeting cognitive and sleep-wake disorders. Also employed in research to develop anti-inflammatory agents due to its ability to influence immune cell activity.
