AdvanSix Di-n-propylamine (DPA)

AdvanSix Di-n-propylamine (DPA) is a colorless, flammable liquid with an ammonia-like odor. It exhibits solubility in water, ethanol, benzene, and ethyl acetate and maintains stability under recommended storage conditions. DPA serves as a key chemical intermediate and acts as a starting material for the synthesis of herbicidal products, including trifluralin, oryzalin, EPTC, and vernolate. Its role in herbicide production highlights its importance in the agricultural and chemical industries.

Storage & Handling

Handling Recommendations
  • Keep containers closed when not in use.
  • Open containers slowly to allow any excess pressure to vent.
  • Keep away from heat, sparks, flame, or other sources of ignition.
  • Protect small containers from physical damage.
  • Use proper electrical grounding and bonding procedures when loading, unloading, and transferring.
  • Use spark-resistant tools.
  • Electrical equipment and circuits in all storage and handling areas must conform to requirements of national electrical code (Articles 500 and 501) for hazardous location.
