Used primarily as a key intermediate in the synthesis of pharmaceuticals, especially in the production of histamine-related compounds and receptor antagonists. Its chiral structure makes it valuable in creating enantiomerically pure drugs, improving efficacy and reducing side effects. Commonly applied in research and development of treatments for allergic reactions, gastric acid secretion disorders, and central nervous system conditions. Also utilized in the preparation of biologically active molecules where imidazole functionality is required for target binding.
