1-(4-Tetrahydropyranyl)-1H-pyrazole-4-boronic acid pinacol ester is a specialized organoboron intermediate used in palladium-catalyzed cross-coupling reactions. Its molecular formula is C16H25BN2O3 (CAS: 1007987-48-5). The core synthesis involves protecting the boronic acid moiety with pinacol and attaching the tetrahydropyranyl group to ensure stability during multi-step pharmaceutical manufacturing.
Store under inert atmosphere at -20°C to prevent hydrolysis. Wear appropriate PPE including nitrile gloves and safety goggles due to potential skin irritation. Avoid contact with strong oxidizers or moisture-sensitive catalysts during handling.
