Used primarily in organic synthesis as a boronic ester reagent for Suzuki-Miyaura cross-coupling reactions. It enables the formation of carbon-carbon bonds, particularly in the construction of biaryl and heteroaryl frameworks found in pharmaceuticals and agrochemicals. The tetrahydro-2H-pyran group enhances solubility and stability, making it suitable for multi-step syntheses and purification processes. Commonly employed in medicinal chemistry for late-stage functionalization of complex molecules.
