Used as an intermediate in the synthesis of liquid crystals and organic semiconductors. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to construct biaryl systems for pharmaceuticals and agrochemicals. Also utilized in the preparation of functionalized aromatic compounds for materials science applications, including OLEDs and conjugated polymers. Its iodo group provides high reactivity in palladium-catalyzed transformations, making it valuable in fine chemical synthesis.
