Used primarily in organic synthesis as a key reagent for cross-coupling reactions, enabling the formation of carbon–phosphorus and carbon–carbon bonds. Its boronate ester group facilitates Suzuki-Miyaura coupling, allowing efficient construction of biaryl and heterobiaryl systems important in pharmaceuticals and agrochemicals. The phosphonate moiety adds versatility for further functionalization or as a precursor to phosphate mimics in bioactive molecules. Commonly employed in the development of novel therapeutic agents and functional materials due to its dual reactivity.
