The Uses of TRIS(2-AMINOETHYL)AMINE

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.

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]. [Beilstein 4 H 256, 4 II 695, 4 III 545, 4 IV 1250.]
