R23 is a HFC, used as a replacement for R13 and R503 in very low-temperature refrigeration. It is also used as a clean fire suppressant as a replacement for Halon 1301. R23 is most commonly used in cascade systems at an evaporating temperature of -60°C to -100°C and at a condensing temperature of approximately -10°C to -40°C. R23 now has limited use due to its high Global Warming Potential (GWP).
