2-Iodoaniline is primarily used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its structure, featuring both an amino group and an iodine atom, makes it a valuable building block for constructing more complex molecules. It is often employed in cross-coupling reactions, such as the Suzuki or Heck reactions, to create carbon-carbon bonds, which are essential in drug development. Additionally, it serves as a precursor in the synthesis of dyes and pigments due to its ability to form stable aromatic compounds. In research, 2-Iodoaniline is utilized to study the effects of halogenated anilines in various chemical processes, contributing to advancements in material science and catalysis.
