Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. Its structure allows for further functionalization, making it valuable in creating biologically active molecules. Commonly employed in research settings for constructing complex organic compounds, especially in medicinal chemistry for designing serotonin or dopamine receptor modulators. Also utilized in the preparation of agrochemicals and specialty chemicals due to its reactive nitrile and halogen groups, which enable diverse chemical transformations.
