Useful:

• Chemical Classes: Solvents -> Chlorofluorocarbons
• Canonical SMILES: C(F)(F)(Cl)Cl
• Inhalation Risk: On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.
• Effects of Short Term Exposure: Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the cardiovascular system and central nervous system. This may result in cardiac disorders and central nervous system depression. Exposure could cause lowering of consciousness.
• Description: Dichlorodifluoromethane is known as CFC-12, also called R-12, or Freon-12. R-12 is a general name for Refrigerant-12. Freon is a trade name for DuPont. CFC stands for chlorofl uorocarbons, which are nontoxic, nonfl ammable, synthetic chemicals containing atoms of carbon, chlorine, and fluorine.CFC use climbed steadily worldwide as it was incorporated in refrigeration and air conditioning, as well as being used as propellants, blowing agents, and solvents. dichlorodifluoromethane structure
• Uses: Refrigerant, aerosol propellant. Dichlorodifluoromethane is used as a refrigerant gas in refrigerators and air conditioners. Dichlorodifluoromethane is also used in aerosol sprays, in plastics, and as an aid in detecting leaks. Dichlorodifluoromethane harms the ozone layer, which protects the earth from the sun’s ultraviolet radiation. Refrigerant; aerosol propellant; plastics; blowing agent Anti-GPR17 has been used in immunohistochemistry.
