Perfluoro(2-methyl-3-pentanone) is a commonly used fire-fighting fluid. The photolysis of Perfluoro(2-methyl-3-pentanone) gives CF3CF2C·(O) and ·CF(CF3)2 radicals. This compound can undergo hydrolysis to produce PFPrA and CF3CFHCF3 (HFC-227ea) in a manner analogous to the Haloform reaction. The atmospheric fate of Perfluoro(2-methyl-3-pentanone) seems to be direct photolysis, which, under low NOx conditions, gives PFPrA a small yield[1]. The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) classifies this chemical as H412 - Harmful to aquatic life with long-lasting effects. Photolysis in sunlight, hydrolysis, and hydration may be a significant sink of Perfluoro(2-methyl-3-pentanone) in the environment.
