Trimethyl borate

Trimethyl borate, or boron trimethoxide, has formula B(OCH3)3. It is a clear liquid. It melts at −34 °C and boils at 68-69 °C. It decomposes in contact with water. It is flammable and burns with a green flame.

It is primarily used as a precursor to boronic esters and boronic acids for Suzuki couplings. Other uses include :
 * 1) Anti-oxidant in Brazing and Solder Flux
 * 2) Wood preservative
 * 3) Catalyst of olefin polymerisation
 * 4) raw material in the production of borophosphosilicate glass film by chemical vapor deposition
 * 5) raw material in the production of specialty glasses using sol-gel technology
 * 6) solvent or catalyst for resins, waxes, paints, and varnishes
 * 7) component of some flame retardants in textile industry
 * 8) component of some welding fluxes
 * 9) in green fire compositions for special effects (as a solution of boric acid in methanol, where it forms in small amounts)
