Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules requiring stereochemical control. Its primary application lies in medicinal chemistry, where it serves as an intermediate for drugs targeting central nervous system disorders and other therapeutic areas. The amine functionality allows for easy derivatization, making it valuable in creating libraries of compounds for drug discovery. The hydrochloride salt form enhances stability and solubility, facilitating handling and use in various reaction conditions.
