Triethylamine (TEA) is a high-purity, tertiary aliphatic amine widely used in organic synthesis, polymer chemistry, HPLC, and industrial manufacturing. As a strong organic base, it is commonly employed in esterification and amidation reactions, particularly for neutralizing acids during the synthesis of esters, amides, and quaternary ammonium salts.
With a purity of ≥99% and low levels of key impurities (ethylamine, ethanol, and diethylamine), Thermo Scientific™ Triethylamine offers reliable performance in synthetic reactions, Swern oxidation, condensation reactions, and HPLC mobile phase modification. Its liquid form is easy to handle and compatible with a wide range of solvents.
