Triethylenetetramine


Triethylenetetramine (TETA and trien), also known as trientine (INN) when used medically, is an organic compound with the formula 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 Wikipedia
