2,3-Difluoro-4-iodoaniline is primarily used in organic synthesis as a building block for more complex chemical compounds. Its structure, featuring both fluorine and iodine atoms, makes it valuable in the development of pharmaceuticals, particularly in the creation of active pharmaceutical ingredients (APIs). The compound is often utilized in cross-coupling reactions, such as Suzuki or Sonogashira couplings, to introduce iodine-containing aromatic systems into drug molecules. Additionally, it serves as an intermediate in the synthesis of agrochemicals, where its unique halogenated structure can contribute to the biological activity of pesticides or herbicides. Its applications also extend to materials science, where it may be used in the development of organic electronic materials or as a precursor for functionalized polymers.
