This compound is primarily utilized in the synthesis of pharmaceuticals, particularly in the development of chiral drugs. Its structure, featuring a benzonitrile group and an aminoethyl moiety, makes it a valuable intermediate for creating active pharmaceutical ingredients (APIs) with specific stereochemistry. It is often employed in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) drugs, where the (R)-enantiomer can provide enhanced efficacy or reduced side effects. Additionally, it serves as a building block in organic synthesis for constructing complex molecules with high enantiomeric purity, which is critical in drug discovery and development processes. Its applications also extend to agrochemical research, where it aids in the design of chiral pesticides and herbicides.
