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)[1]
