Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its dual halogen functionality allows for selective cross-coupling reactions, enabling the construction of complex aromatic structures. Commonly employed in Suzuki and Heck reactions to introduce substituted benzyl groups. Also utilized in the development of radiolabeled compounds for medicinal imaging due to the presence of iodine, which can be easily substituted with radioactive isotopes. Its reactivity makes it valuable in the synthesis of functionalized polymers and liquid crystals.
