Chemical Properties

Formula Weight
Melting point
Slightly soluble in water.


It is a useful intermediate in pharmaceutical intermediate. Boronic Acids are important chemical building blocks employed in cross coupling reactions. The ability of boronic acids to reversibly bind diol functional groups has been utilized for fluorescent detection of saccharides. The compound Bortezomib utilizes the boronic acid for its proteasome inhibitory effect.


Store in cool dry place. Ensure proper ventilation. Incompatible with oxidizing agents.
