Used primarily in organic synthesis as a boronic ester coupling partner in Suzuki-Miyaura cross-coupling reactions. It enables the formation of biaryl and conjugated systems, which are key structural motifs in pharmaceuticals, agrochemicals, and advanced materials. The ester groups allow further functionalization, making it useful in the preparation of polymers, liquid crystals, and metal-organic frameworks. Its boronate ester group provides good stability and reactivity under palladium catalysis, facilitating efficient carbon-carbon bond formation in research and industrial settings.
