This compound is primarily utilized in pharmaceutical research and development, particularly as an intermediate in the synthesis of active pharmaceutical ingredients (APIs). Its chiral structure makes it valuable in the production of enantiomerically pure drugs, which are crucial for ensuring high efficacy and reduced side effects in therapeutic applications. It is often employed in the preparation of compounds targeting neurological and psychiatric disorders, such as antidepressants and anxiolytics. Additionally, its benzonitrile moiety can serve as a versatile building block in organic synthesis, enabling the creation of complex molecules with potential biological activity. The hydrochloride form enhances its stability and solubility, making it more suitable for various chemical processes and formulations.
