Used as a reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. It serves as a stable boronate partner for palladium-catalyzed coupling with aryl or vinyl halides, commonly applied in the preparation of pharmaceuticals, agrochemicals, and advanced materials. The pinacol ester group enhances stability and handling compared to the free boronic acid, making it suitable for multi-step syntheses and industrial-scale processes.
