Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic acetylcholine receptor modulators such as varenicline for nicotine addiction treatment. It plays an important role in the development of drugs targeting neurological disorders including Alzheimer's disease, schizophrenia, and smoking cessation therapies. Its enantiomeric purity enhances the selectivity and efficacy of the final active pharmaceutical ingredient. Also utilized in agrochemicals as an intermediate for the development of selective pesticides, such as neonicotinoids, due to its contribution to the stability and specific binding affinity of the final products to biological targets.
