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 for complex aromatic systems. Also employed in the development of functional materials, including organic semiconductors and liquid crystals, due to its rigid naphthalene core and ease of functionalization. Its bromine group allows for selective metalation or substitution, making it valuable in fine chemical synthesis.
