R23
R-23 most commonly refers to trifluoromethane, a halogenated hydrocarbon refrigerant designated with the R-23 code. Its chemical formula is CHF3 (trifluoromethane). It is a non-flammable, colorless gas used in low-temperature refrigeration systems, particularly for ultra-low-temperature applications such as certain industrial freezers and cryogenic cooling processes. R-23 has a boiling point of about minus 82 degrees Celsius at standard pressure. It has zero ozone depletion potential, but a very high global warming potential, which has led to environmental regulation and efforts to minimize leaks and to substitute it with lower-GWP alternatives where feasible. Handling requires trained personnel and appropriate safety and containment measures, since extremely cold vapors can cause frostbite and equipment must remain sealed to prevent emissions.
R-23 is also a designation used for routing in transportation networks, where the code designates regional
