3-Carboxyphenylboronic acid (CAS: 1207-89-4) is a specialized organoboron intermediate with molecular formula C7H7BO4. It is synthesized via directed lithiation of m-xylene followed by borylation and oxidation, serving as a critical building block for cross-coupling reactions.
Store under inert atmosphere at 2-8°C to prevent hydrolysis. Avoid direct skin contact; use appropriate PPE including nitrile gloves and safety goggles due to potential irritant properties.
