Used as a reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds between aromatic systems. Its cyclic boronate structure offers enhanced stability and reactivity, making it valuable in the preparation of biaryl compounds for pharmaceuticals, agrochemicals, and advanced materials. It serves as a naphthalene coupling partner in the synthesis of conjugated organic molecules used in optoelectronics and liquid crystals.
