Widely used in organic synthesis, especially in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds between aromatic rings. It acts as a key building block for constructing conjugated organic materials such as polymers and small molecules used in organic electronics. Commonly applied in the development of organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and semiconducting materials due to its stability and reactivity. Its boronate ester groups allow for efficient and selective coupling under mild conditions, making it valuable in pharmaceutical and agrochemical synthesis as well.
