Used as a key intermediate in the synthesis of boron-containing pharmaceuticals, 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 targeted drug design. Also employed in Suzuki-Miyaura cross-coupling reactions as a building block for biaryl compounds in medicinal chemistry. Shows utility in creating sensors for sugar detection due to boronic acid’s affinity for diols.
