4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (CAS: 860079-83-2) is a specialized heterocyclic boronic ester used in palladium-catalyzed cross-coupling reactions. It serves as a critical building block for synthesizing complex pharmaceutical intermediates via Suzuki-Miyaura coupling methodologies.
Store under inert atmosphere at temperatures below -20°C to prevent hydrolysis. Use appropriate PPE including nitrile gloves and safety goggles; avoid contact with skin and eyes due to potential irritant properties.
