Used primarily in organic synthesis as a boronic ester reagent for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds between aromatic systems. Its pyrrolidine-substituted phenylboronate structure allows for the introduction of nitrogen-containing heterocyclic motifs into biaryl frameworks, which are common in pharmaceuticals and agrochemicals. The compound is valued for its stability and reactivity under palladium catalysis, making it suitable for constructing complex molecules in drug discovery and materials science. It is also employed in the synthesis of functionalized organic semiconductors and ligands for metal complexes.
