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.
