Triethyl borate is widely used as a precursor in the synthesis of various boron-containing compounds. It plays a key role in the production of borate esters, which are essential in the manufacture of flame retardants, lubricants, and plasticizers. In the electronics industry, it is utilized in the preparation of thin-film coatings for semiconductors and optical materials, enhancing their performance and durability. Additionally, it serves as a cross-linking agent in the production of specialty polymers and resins, improving their thermal and chemical stability. In organic synthesis, triethyl borate acts as a reagent for the introduction of boron atoms into molecules, facilitating reactions such as hydroboration and transesterification. It is also employed in the formulation of adhesives and sealants, where it contributes to improved bonding strength and moisture resistance.
