Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block in cross-coupling reactions, such as Suzuki and Heck reactions, enabling the formation of carbon-carbon bonds. Its iodo functionality provides high reactivity in palladium-catalyzed transformations, making it valuable in the development of complex aromatic compounds. Also employed in the synthesis of liquid crystals and functional materials due to its stable aromatic core and tunable substituents.
