Storage & Sensitivity
Hygroscopic. Store under Argon. Ambient temperatures.
Slightly soluble in water.


Benzeneboronic acid is widely utilized in various cross coupling reactions for example Mizoroki-Heck and Suzuki-Miyaura coupling reactions, etc. It serves as a receptor for carbohydrates, antimicrobial agents and enzyme inhibitors in biological reactions. It acts as a reagent in palladium-catalyzed stereoselective Heck-type reaction and as a catalyst in Ni(II) pincer complex and Pd(II) pyridoxal hydrazone metallacycles. It is also employed as a sensor for neutron capture therapy for cancer, transmembrane transport and bioconjugation and labeling of proteins and cell surface.


Hygroscopic. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents. Avoid moisture exposure.
