Used as a boronic ester reagent in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds in organic synthesis. It serves as a stable, lipophilic precursor for generating 3-methylbenzylboronic acid in situ, enabling the preparation of substituted aromatic and heteroaromatic compounds. Commonly applied in pharmaceutical and agrochemical research for constructing biaryl intermediates. Its tetramethyl-substituted dioxaborolane ring enhances stability and handling compared to more sensitive boronic acids.
