Description and Uses

Triethylenetetramine (TETA and trien) also known as trientine (INN) when used medically, is an organic compound with the formula [CH2NHCH2CH2NH2]2. The pure freebase 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 Triethylenetetramine. The hydrochloride salts are used medically as a treatment for copper toxicity.

Triethylenetetramine is used as an amine hardener in epoxy resin of the bisphenol A type.It is used in synthesis of detergents, softeners, and dyestuffs; manufacture of pharmaceuticals; vulcanization accelerator of rubber; thermo setting resin; epoxy curing agent; lubricating-oil additive; analytical reagent for Cu, Ni; chelating agent; treatment of Wilson's disease.
