Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) due to its reactive iodine group, which allows for coupling reactions in cross-coupling processes like Suzuki or Heck reactions. Commonly employed in research and development of new medicinal compounds, especially in creating analogs of pyridine-based bioactive molecules. Also utilized in agrochemicals for the synthesis of certain pesticides and herbicides. Its methyl group enhances reactivity and selectivity in various synthetic pathways.
