Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring stereochemical control. Commonly employed in the production of antidiabetic drugs, such as DPP-4 inhibitors for type 2 diabetes treatment. Also utilized in the preparation of bioactive molecules and intermediates for medicinal chemistry due to its amine functionality and structural rigidity. Its salt form enhances stability and handling during industrial processes.
