Used as a reagent in organic synthesis, particularly in cross-coupling reactions like Suzuki-Miyaura couplings, which are essential for forming carbon-carbon bonds in the production of pharmaceuticals, agrochemicals, and advanced materials. Its stability and reactivity make it a valuable intermediate in the synthesis of complex organic molecules, enabling the introduction of the 4-bromophenyl group into target compounds. Additionally, it is employed in the development of boron-containing compounds for use in medicinal chemistry and material science research.
