Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring chiral amine functionalities. Its structure supports the creation of complex molecules in drug discovery, especially in central nervous system agents and kinase inhibitors. The hydrochloride salt form enhances stability and solubility, making it suitable for use in various reaction conditions and purification processes. Commonly employed in medicinal chemistry for scaffold modification and lead optimization due to its favorable steric and electronic properties.
