  • Store in a cool, well-ventilated area away from heat, sparks, open flames, and other ignition sources.

  • Keep containers tightly closed and use compatible storage materials.

  • Avoid contact with strong acids, oxidizing agents, and other incompatible substances.

  • Use appropriate personal protective equipment and suitable ventilation.

  • Follow the product Safety Data Sheet (SDS) and applicable regulations for storage, handling, and transportation.

5. Conclusion

Diethylamine (CAS No. 109-89-7) is an important secondary amine used in pharmaceutical, agrochemical, rubber, and specialty chemical manufacturing. Its versatility makes it valuable as an industrial chemical intermediate. However, its high flammability, volatility, and corrosive properties require careful handling and appropriate safety management.

For commercial applications, buyers should confirm product purity, specifications, packaging, and documentation with their supplier before placing an order.
