Used in medicinal chemistry as a key intermediate for synthesizing boron-containing compounds, particularly in the development of proteasome inhibitors for cancer therapy. Its boronic acid group enables reversible binding to enzyme active sites, making it valuable in designing drugs targeting serine proteases. Also applied in Suzuki-Miyaura cross-coupling reactions for constructing biaryl frameworks in pharmaceutical research. Soluble in polar solvents, which facilitates its use in aqueous reaction conditions common in bioconjugation and labeling techniques.
