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 bromine functionality allows for selective metalation and further functionalization, making it valuable in the development of complex aromatic compounds. Also employed in the synthesis of specialty polymers and liquid crystals due to its stable aromatic core and steric bulk from the tert-butyl group.
