Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its structure supports the formation of complex molecules in central nervous system agents and metabolic disease treatments. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles. Also utilized in the preparation of intermediates for kinase inhibitors and other biologically active compounds. The hydrochloride salt form enhances stability and solubility, facilitating handling in industrial processes.
