Description

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.

Application

Building block for cryptands; precursor to a proazaphosphatrane, a stong, nonionic base.

TREN can be grafted with multi-walled carbon nanotube (MWCNT) for use in solid phase extraction of metal ions for wastewater treatment based applications. It can also be used as a chelating agent in the surface treatment of silica nanoparticles which can further be used for a wide range of industrial applications.
