What is Trisaminoethylamine?
Trisaminoethylamine (CAS 4097-89-6), commercially known as TREN, is a tetradentate triamine.
Where is Trisaminoethylamine used?
- Coatings and adhesives: curing agent and cross-linker for epoxy systems
- Water treatment: chelating agent that sequesters heavy metal ions
- Polymer manufacturing: ligand in atom transfer radical polymerization (ATRP)
- Lubricants and metalworking fluids: metal-complexing capacity
- Its four nitrogen donor sites chelate metal ions and initiate controlled polymerization reactions.
Good to know: Buyers for sensitive polymer or coordination chemistry applications should confirm purity specifications directly with the supplier.
Commercial specifications
- Purity typically 96–99% depending on application tier
