Used primarily in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) for therapeutic drugs. It serves as a key intermediate in the production of certain antidepressants and antipsychotic medications, aiding in the modulation of neurotransmitter activity in the brain. Additionally, it finds application in organic chemistry research for the study of nitrile-containing compounds and their reactivity. Its role in the creation of complex molecules makes it valuable in medicinal chemistry and drug discovery processes.
