Used as a coupling reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a stable and easy-to-handle source of the 2-methoxyethyl group, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical intermediates. Its trifluoroborate structure offers enhanced stability and reduced toxicity compared to traditional boronic acids, making it suitable for late-stage functionalization in complex molecule synthesis. Soluble in aqueous and organic solvents, it allows for flexible reaction conditions and efficient purification processes.
