Used as a key intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Stille, and Negishi couplings. Its dual halogen functionality allows selective sequential reactions—iodine reacts first under mild conditions, while bromine can be activated later for further derivatization. This makes it valuable in the construction of complex aromatic systems found in pharmaceuticals, agrochemicals, and advanced materials. Commonly employed in the development of liquid crystals, organic semiconductors, and bioactive molecule scaffolds due to its stable tert-butyl group that influences steric and electronic properties.
