2-Methoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS: 76193-60-5), also known as methoxyboronic acid pinacol ester, is a versatile organoboron reagent widely utilized in cross-coupling chemistry. It serves as a stable source of the methoxy group or acts as a boronate intermediate for Suzuki-Miyaura reactions. The compound features a pinacol protecting group enhancing stability during synthesis.
Store under inert atmosphere at controlled temperatures to prevent hydrolysis. Avoid direct skin contact and inhalation; use appropriate PPE including respirators and chemical-resistant gloves. Do not dispose of waste into water systems due to potential environmental toxicity.
