What is N,N-bis(3-aminopropyl)methylamine?
N,N-bis(3-aminopropyl)methylamine (CAS 105-83-9), also known commercially as methyldipropylenetriamine, is a trifunctional amine used as a reactive building block and curing agent.
Where is N,N-bis(3-aminopropyl)methylamine used?
- Epoxy coatings and adhesives: curing agent that builds chemical resistance
- Water treatment: sequesters metal ions and inhibits corrosion in cooling water and oilfield systems
- Lubricants and metalworking fluids: corrosion inhibitor protecting ferrous and non-ferrous surfaces
- Polymer synthesis: monomer or chain extender for polyamide and polyurea systems
- Its three amine groups enable crosslinking, chelation and corrosion inhibition.
Commercial specifications
- Technical grade, purity typically 98% or higher
- Bulk quantities in drums and IBC containers
