Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, as a boronic ester precursor for constructing biaryl and aryl-heteroaryl frameworks. Its ester functionality allows further transformation, such as hydrolysis or reduction, enabling versatile derivatization in pharmaceutical and agrochemical research. The pinacol boronate group provides stability and ease of handling, making it a valuable reagent in medicinal chemistry for building complex molecules.
