2,4-Dichloro-3-iodoaniline is a halogenated aniline derivative with the molecular formula C?H?Cl?IN. This compound serves as a versatile intermediate in organic synthesis, particularly in the preparation of agrochemicals, pharmaceuticals, and specialty chemicals. Its distinct substitution pattern—featuring chlorine and iodine atoms at the 2, 4, and 3 positions—enhances reactivity in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig couplings, enabling precise functionalization. The iodine moiety offers further derivatization potential via halogen exchange. High purity grades ensure consistent performance in research and industrial applications. Proper handling is advised due to potential sensitivity to light and moisture. Storage under inert conditions is recommended to maintain stability.
