Used in the synthesis of covalent inhibitors targeting serine hydrolases and other enzyme classes, particularly in pharmaceutical research for developing activity-based probes. Its boronic acid moiety enables reversible binding to catalytic serine residues, making it valuable in drug design for diseases involving protease or esterase activity. Commonly employed in bioconjugation strategies for labeling proteins and in the development of sensors for detecting biologically relevant molecules. Also utilized in Suzuki-Miyaura cross-coupling reactions during the preparation of complex organic molecules in medicinal chemistry.
