Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to construct biaryl compounds for pharmaceuticals and agrochemicals. Its dual halogen functionality allows sequential coupling reactions, enabling the stepwise assembly of complex aromatic structures. Commonly employed in the development of drug intermediates and functional materials where precise molecular architecture is required. The boronic acid group provides stability and reactivity under mild conditions, making it suitable for late-stage functionalization in medicinal chemistry.
