Used as a key intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling, enabling the formation of biaryl structures important in pharmaceuticals and agrochemicals. Its trimethylsilyl group acts as a directing or protecting group in functionalization reactions, enhancing regioselectivity. Also employed in the preparation of advanced materials, including organic semiconductors and liquid crystals, due to its ability to modulate electronic properties and improve solubility in conjugated systems.
