Used in the synthesis of pharmaceutical intermediates, particularly in the development of chiral drugs where stereochemistry plays a critical role in biological activity. Its amine functionality and chiral center make it valuable in asymmetric synthesis and as a building block for bioactive molecules. Commonly employed in medicinal chemistry for optimizing drug candidates targeting central nervous system disorders. The hydrochloride salt form enhances stability and solubility, facilitating handling and formulation in early-stage drug development.
