What is Diethylhexylamine?
Diethylhexylamine (CAS 106-20-7), also known as di-(2-ethylhexyl)amine, is a branched secondary amine used as a catalyst, curing agent, and chemical intermediate.
Where is Diethylhexylamine used?
- Coatings and adhesives: curing agent and crosslinker
- Epoxy and polyurethane systems: influences cure speed and film integrity
- Catalyst precursor in synthesis of specialty chemicals requiring controlled basicity
- Personal care: neutralizing agent and intermediate for emulsifiers and conditioning actives
- Flavor and fragrance: building block for nitrogen-containing aroma compounds
- Its long-chain structure suits applications needing controlled reactivity and compatibility with non-polar systems.
Commercial specifications
- High purity levels for industrial and specialty chemical applications
- Technical grade standard; higher-purity specifications for sensitive synthesis
- Packaging: drums to IBC containers depending on order volume and logistics
