Trisaminoethylamine

Trisaminoethylamine (CAS 4097-89-6), commercially known as TREN, is a tetradentate triamine used across polymer chemistry, metal treatment, and specialty formulation. Its four nitrogen donor sites make it effective for chelating metal ions and initiating controlled polymerization reactions in various industrial and laboratory settings.

In coatings and adhesives, TREN functions as a curing agent and cross-linker for epoxy systems, contributing to network density and adhesion performance in demanding industrial formulations. Water treatment operations use it as a chelating agent to sequester heavy metal ions, preventing scale formation and equipment fouling in process water circuits during operation.

In polymer manufacturing, TREN serves as a ligand in atom transfer radical polymerization (ATRP), enabling precise molecular weight control in specialty plastics and elastomers. Lubricant and metalworking fluid formulators incorporate it for its metal-complexing capacity, helping to stabilize formulations and protect metal surfaces under high-load conditions.

Trisaminoethylamine is supplied as a liquid. Technical grade is the standard commercial offering, with purity levels typically specified at 96–99% depending on the application tier. Buyers sourcing for sensitive polymer or coordination chemistry applications should confirm purity specifications directly with the supplier to ensure the material meets requirements.
