Colorless liquid | [Uses]
Tris(2-aminoethyl)amine is a tetradentate chelating ligand and forms stable complexes with transition metals. It is also used as a carbon dioxide absorbent. Further, it acts as a reagent for cleavage of the fluorenylmethyloxycarbonyl (Fmoc) group in peptide synthesis. It reacts with aryl isocyanates and isothiocyanates to give tris-urea and -thiourea derivatives. | [Definition]
ChEBI:Tris(2-aminoethyl)amine is a tetramine. | [General Description]
Tris(2-aminoethyl)amine (TREN) is a water soluble tripodal ligand that is majorly used in co-ordination chemistry. It has three aminoethylgroups that attach with the surface atoms to provide a scaffold assembly. | [Purification Methods]
For a separation from a mixture containing 62% TRIEN, see entry under triethylenetetramine. Also purify it by conversion to the hydrochloride (see below), recrystallise it and regenerate the free base [Xie & Hendrickson J Am Chem Soc 109 6981 1987].
