Remarks

Cyclohexane p.d.a. is a highly pure organic solvent used, among others, in chemical analysis, laboratories, and the chemical industry. Due to its high volatility and flammability, it should be stored in tightly closed containers, away from ignition sources, in a cool and well-ventilated place. Contact with skin and eyes should be limited by using appropriate personal protective equipment.
