This compound is primarily utilized in the pharmaceutical industry as a chiral intermediate in the synthesis of various active pharmaceutical ingredients (APIs). Its structure, featuring a benzonitrile group and an aminoethyl moiety, makes it a valuable building block for the development of enantiomerically pure drugs, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) targeting medications. Additionally, it is employed in research settings for the study of receptor binding and enzyme inhibition, aiding in the discovery of new therapeutic agents. Its hydrochloride form enhances solubility, facilitating its use in aqueous-based reactions and formulations.
