Dichlorodifluoromethane

Dichlorodifluoromethane (CAS 75-71-8), commercially known as R-12 or Refrigerant 12, is a chlorofluorocarbon compound used historically as a refrigerant, aerosol propellant, and solvent carrier.

Where is Dichlorodifluoromethane used?

• Aerospace and defense: solvent carrier in specialized cleaning and surface preparation where legacy equipment requires CFC-based formulations
• Automotive: original-spec refrigerant for pre-1994 vehicle air conditioning systems not retrofitted to alternatives
• Calibration equipment, reference standards, and maintenance of older refrigeration systems operating under original design parameters
• Procurement is driven by service and maintenance demand rather than new manufacturing integration.

Good to know: Supply is subject to national and regional regulatory controls, with recovered and reclaimed grades predominant in most jurisdictions. Compliance with environmental protocols is essential for all transactions.

Commercial specifications

• Cylinders and drums sized for industrial use
• Buyers must verify documentation and handling procedures for controlled chemical substances
