Also known as TETA, N'-[2-(2-azanylethylamino)ethyl]ethane-1,2-diamine, 2-aminoethyl-[2-(2-aminoethylamino)ethyl]amine, N'-[2-(2-aminoethylamino)ethyl]ethane-1,2-diamine, triethylene tetramine, trientine, trien
Triethylenetetramine (TETA and trien), also known as trientine (INN) when used medically, is an organic compound with the formula [CH2NHCH2CH2NH2]2. The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation. It is soluble in polar solvents. The branched isomer tris(2-aminoethyl)amine and piperazine derivatives may also be present in commercial samples of TETA. The hydrochloride salts are used medically as a treatment for copper toxicity.

==Uses== ===Epoxy uses=== The reactivity and uses of TETA are similar to those for the related polyamines ethylenediamine and diethylenetriamine. It is primarily used as a crosslinker ("hardener") in epoxy curing. TETA, like other aliphatic amines, react quicker and at lower temperatures than aromatic amines due to less negative steric effects since the linear nature of the molecule provides it the ability to rotate and twist.
