Used primarily in the synthesis of pharmaceutical intermediates, particularly in the development of histamine H3 receptor antagonists. It serves as a key building block in medicinal chemistry for drugs targeting neurological disorders such as narcolepsy, ADHD, and Alzheimer's disease. Its structure mimics imidazole-based neurotransmitters, making it valuable in designing bioactive molecules with enhanced receptor selectivity. Also employed in the preparation of agrochemicals and functional materials due to its stable heterocyclic core and amine reactivity.
