Used in Suzuki-Miyaura cross-coupling reactions as a boron-containing reagent to form carbon-carbon bonds in organic synthesis. The presence of the nitrophenyl group enhances reactivity and allows further functionalization, making it valuable in pharmaceutical and agrochemical research for building complex aromatic and heteroaromatic systems. Its boronic ester moiety offers stability and ease of handling compared to boronic acids, improving yield and reproducibility in coupling processes.
