Used as a key reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a boronic ester derivative that enables the formation of carbon-carbon bonds, especially in the construction of biaryl frameworks found in pharmaceuticals and agrochemicals. Its electron-rich trimethoxyphenyl group enhances stability and influences reactivity, making it valuable in the synthesis of complex aromatic systems. Commonly employed in late-stage functionalization due to its compatibility with various functional groups and moderate reaction conditions.
