CAS 121-43-7: Trimethyl borate

Description: Trimethyl borate, with the CAS number 121-43-7, is an organoboron compound characterized by its molecular formula C3H9BO3. It appears as a colorless, volatile liquid with a sweet odor, and it is soluble in organic solvents such as ethanol and ether. Trimethyl borate is primarily used as a reagent in organic synthesis, particularly in the production of boron-containing compounds and as a methylating agent. It can also serve as a precursor for the synthesis of boron esters and is utilized in the manufacture of certain types of glass and ceramics. The compound is flammable and should be handled with care, as it can release toxic fumes upon combustion. Additionally, it is known to hydrolyze in the presence of water, forming boric acid and methanol. Due to its reactivity, appropriate safety measures should be taken when working with trimethyl borate, including the use of personal protective equipment and working in a well-ventilated area.
