Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic systems. The bulky tert-butyl groups provide steric hindrance, which can direct regioselectivity in further derivatizations. It is also employed in the development of specialty polymers and ligands for catalysts, where steric bulk and electronic properties are important.
