Used in organic synthesis as a building block for cross-coupling reactions, particularly in Suzuki-Miyaura coupling, to construct biaryl compounds. Its bromine substituents allow for selective sequential coupling, enabling the synthesis of complex aromatic structures. Commonly applied in the development of pharmaceuticals, agrochemicals, and functional materials where halogenated aryl motifs are required. The boronic acid group also facilitates conjugation with diols, useful in sensor design and bioconjugation chemistry.
