Applications
Trimethyl borate is a useful reagent in organic synthesis. It is involved in the production of resins, waxes and paints and acts as a methylation agent. As a boron source, it is used to prepare flame retardants, anti-oxidants and corrosion inhibitors. It reacts with Grignard reagents followed by hydrolysis to prepare boronic acid. It is also used as a precursor of borate esters, which finds application in Suzuki coupling reaction. It is an intermediate in the preparation of sodium borohydride.

Solubility
Miscible with tetrahydrofuran, ether, isoporpylamine, hexane and methanol.

Notes
Moisture sensitive. Keep container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents. It decomposes slowly in the presence of moisture and rapidly in water.
