Dichlorodifluoromethane (R-12 Refrigerant)
Dichlorodifluoromethane, also known as R-12 or Freon-12, is a perhalogenated acyclic hydrocarbon containing only fluorine and chlorine halogens, classified under HTS 2903.77.0050 as a halogenated derivative of hydrocarbons. It was widely used as a refrigerant in automotive and domestic air conditioning systems before being phased out due to ozone depletion concerns. Now primarily imported for servicing legacy equipment or as a chemical intermediate.
