AdvanSix Cyclohexylamine (MCHA)

AdvanSix Cyclohexylamine (MCHA) is a colorless, flammable liquid with an ammonia-like odor and is a vital intermediate in organic compound production. Soluble in water, ethanol, benzene, and ethyl acetate, it remains stable under recommended storage conditions. Widely used in various industries, it inhibits corrosion in boiler feed water and serves as a key component in the manufacturing of insecticides, plasticizers, soaps, rubber chemicals, dyes, and gas absorbents.

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.
