Tetraethylenepentamine from TCI (product code T0098) is an aliphatic polyamine from the ethyleneamine family. Its molecule carries many primary and secondary amine groups linked by ethylene bridges. As the product name states, this material is a mixture of branched chain isomers and cyclic compounds rather than a single defined structure, which is typical of higher ethyleneamines. In the laboratory it serves as a nitrogen-rich building block, a metal-chelating ligand, an epoxy resin hardener, and an amine functionalization agent for materials.
Researchers choose this material for its high density of amine groups. Because each molecule holds many nitrogen atoms, it can bind metal ions strongly and react readily with epoxide, isocyanate, aldehyde, and acyl groups. The amine groups are also basic and can capture carbon dioxide, which is why the material is widely studied as a component of CO2 capture sorbents. It is a viscous liquid, so it is easy to impregnate into porous materials or blend into resin formulations without first dissolving a solid.
In Indonesia, Tetraethylenepentamine is widely used in chemical engineering and materials chemistry laboratories that work on carbon capture, heavy metal adsorbents, and amine-modified functional materials. University research groups and industrial R&D laboratories use it to prepare amine-impregnated supports, study curing behaviour in epoxy systems, and synthesize nitrogen-rich intermediates. Supplied under the TCI brand, it gives these laboratories a consistent starting material for comparative experiments and method development.

- CO2 capture sorbent research: the basic primary and secondary amine groups react with carbon dioxide, and the liquid can be impregnated into porous supports to build solid amine sorbents.
- Metal chelation and heavy metal adsorbents: the many nitrogen atoms in each molecule bind metal ions strongly, making it useful as a ligand or as a grafted chelating site.
- Epoxy resin curing studies: its multiple reactive amine hydrogens open epoxide rings and crosslink resins, and its liquid form blends easily into formulations.
- Amine functionalization of materials: it reacts with epoxide, isocyanate, aldehyde, and acyl groups on surfaces or polymers, introducing a high density of amine sites.
- Nitrogen-rich building block in synthesis: as a non-heterocyclic building block with several amine groups, it provides a convenient starting point for polyamine derivatives and related intermediates.

Keep Tetraethylenepentamine in its original, tightly closed container in a cool, dry, well-ventilated area, away from acids, oxidizing agents, and other incompatible materials. Amines can absorb carbon dioxide and moisture from the air, so keep containers sealed between uses and minimize headspace exposure. Because the material is basic and can irritate or burn the skin and eyes, handle it in a fume hood while wearing chemical-resistant gloves, safety goggles, and a lab coat. Always check the TCI Safety Data Sheet for specific hazard, storage, and disposal instructions before use.
