Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronate ester group facilitates mild and selective coupling with aryl halides, making it valuable in constructing biaryl structures found in active pharmaceutical ingredients. Commonly employed in late-stage functionalization due to stability and compatibility with various functional groups. Also applied in materials science for synthesizing organic semiconductors and conjugated polymers.
