Used as a key building block in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules, particularly in the development of pharmaceuticals, agrochemicals, and advanced materials. Its dual boronate ester groups allow for sequential or simultaneous coupling with aryl halides, making it valuable in creating biaryl and terphenyl structures found in functional organic compounds. Widely applied in research and industrial settings for constructing conjugated systems in organic electronics and liquid crystals.
