Application

Trimethyl borate, a versatile moisture-sensitive liquid, serves a vital role in organic synthesis. It is integral in the production of resins, waxes, and paints, acting as a methylation agent and boron source. In its interaction with Grignard reagents, it facilitates the production of boronic acids, which are essential in cross-coupling reactions like the Suzuki and Chan-Lam couplings. Furthermore, it acts as a precursor for borate esters, which are significant in these reactions. Trimethyl borate also contributes to the preparation of sodium borohydride and serves as a neutron detector gas when used alongside a scintillation counter. Its ability to decompose into methanol and boric acid in water further enhances its utility in various chemical processes, such as the formation of flame retardants, antioxidants, and corrosion inhibitors.
