What is Tetrakis(2-hydroxypropyl)ethylenediamine?
Tetrakis(2-hydroxypropyl)ethylenediamine (CAS 102-60-3) is a multifunctional amine alcohol for chelation, pH buffering and crosslinking.
Where is Tetrakis(2-hydroxypropyl)ethylenediamine used?
- Water treatment: sequesters heavy metal ions, preventing scale and improving process water quality
- Coatings and adhesives: crosslinking agent and curing component in epoxy and polyurethane systems
- Home care and industrial cleaning: chelating agent that deactivates hardness ions, improving surfactant efficiency and formulation stability
- Plastics and polymers: reactive intermediate or stabilizer that modifies network structure and processing behaviour
- Its amine and hydroxyl groups sequester metal ions and act as a reactive building block in polymer systems.
Commercial specifications
- Technical grade, concentrations typically around 85–100%
- Bulk supply in drums and intermediate bulk containers (IBCs)
