Description

Dichlorodifluoroethene (CAS: 598-88-9) is a halogenated hydrocarbon with the molecular formula C₂Cl₂F₂, also known by its IUPAC name 1,2-dichloro-1,2-difluoroethene. This compound is a colorless, volatile liquid or gas under standard conditions, characterized by its high stability and low reactivity due to the presence of strong carbon-chlorine and carbon-fluorine bonds. It is commonly used as an intermediate in organic synthesis, particularly in the production of fluoropolymers and refrigerants. Dichlorodifluoroethene is stored in tightly sealed containers to prevent evaporation and degradation. Suitable for laboratory and industrial applications, this chemical should be handled with appropriate safety measures, including fume hoods and personal protective equipment (PPE).

• Physical Description: Dichlorodifluoroethylene is a liquid material, which may cause illness from inhalation. When heated to high temperatures it may decompose and emit toxic fumes. When in contact with water or steam it may produce additional fumes that can cause illness from inhalation. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams.
