Used in the synthesis of pharmaceutical intermediates, particularly in the development of histamine H3 receptor antagonists. It serves as a chiral building block in drug discovery for neurological disorders such as narcolepsy, ADHD, and Alzheimer's disease. Its structural features enable selective binding to receptors in the central nervous system, making it valuable in creating compounds with improved efficacy and reduced side effects. Also employed in asymmetric synthesis due to its chiral amine functionality, supporting the production of enantiomerically pure drugs.
