Used in organic synthesis as a key reagent for Suzuki-Miyaura cross-coupling reactions, typically in its pinacol ester form for enhanced stability, enabling the formation of carbon-carbon bonds. The boronate group facilitates coupling with aryl halides, making it valuable in constructing complex molecules for pharmaceuticals and materials science. Also employed in the development of sensors and probes due to its ability to interact with diols and sugars (upon hydrolysis if needed), aiding in biochemical research and diagnostics. Its stability and reactivity make it a versatile tool in medicinal chemistry for drug discovery and development.
