Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of centrally acting agents such as certain antidepressants and antipsychotics. Its stereochemistry plays a critical role in enhancing the selectivity and efficacy of active pharmaceutical ingredients. Commonly employed in asymmetric synthesis due to the amine functionality, which allows for coupling reactions in drug development. Also utilized in the preparation of catalysts for enantioselective transformations in medicinal chemistry.
