| TRIS(2-AMINOETHYL)AMINE Usage And Synthesis |
| Chemical Properties | 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. | | 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. | | Hazard | A poison by ingestion and skin contact. | | Safety Profile | A poison by ingestion
and skin contact. When heated to
decomposition it emits toxic vapors of NOx. | | 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].
