1,4-Phenylenediboronic acid pinacol ester (CAS 25890-67-3) is a key organoboron intermediate with formula C14H20B2O4. Synthesized via Pd-catalyzed borylation of 1,4-dibromobenzene, it serves as a stable boron source for Suzuki-Miyaura cross-coupling reactions.
Store under inert atmosphere at -20°C to prevent hydrolysis. Use appropriate PPE; avoid contact with moisture or oxidizers. Not approved for direct clinical use as a drug substance.
