Bromodifluoromethane or Halon 1201 or FC-22B1 is a gaseous trihalomethane or a hydrobromofluorocarbon.

It can be prepared be reaction of hydrogen and dibromodifluoromethane at temperature in range 400–600 °C.[1]

Critical point data: Tc = 138.83 °C (411.98 K); pc = 5.2 MPa (51.32 bar); Vc = 0.275 dm3.mol−1.

Bromodifluoromethane was used as a refrigerant and in fire extinguishers. It is a class I ozone depleting substance with ozone depletion potential ODP = 0.74. It was banned by Montreal Protocol in 2000.
