Fluoroform CHF3; CAS number, also known as trifluoromethane, is one of the haloalkanes with zero ozone depletion, as it does not contain any chlorine. As a refrigerant, it is known as R-23 or HFC-23. In the semiconductor industry, it is also used in plasma etching of silicon oxide or silicon nitride.
HFC-23 is also used as a replacement for Halon 1301 in fire suppression systems as a total flooding gaseous fire suppression agent. When used as a fire suppressant, the chemical carries the DuPont trade name, [FE-13™]
Fluoroform is the IUPAC preferred name for this compound.
