FK-5-1-12 is a fluorinated ketone with the systematic name 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone and the structural formula CF3CF2C(=O)CF(CF3)2, a fully-fluorinated analog of ethyl isopropyl ketone.
It does not deplete ozone (ODP 0) and has a global warming potential of 1 (with a lifetime of 80 years), equivalent to that of carbon dioxide. 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 and hydration may be a significant sink of Novec 1230 in the environment.
It is used as gaseous fire suppression agent in scenarios where water-based fire suppression (for example, from a fire sprinkler) would be impractical or where it could damage expensive equipment or property, such as museums, server rooms, banks, clean rooms and hospitals. It can be used in both total/partial/localized flooding systems, and directional spray type applications; it is also used in portable extinguishers for specialized applications. It has been used as a full-immersion fluid in a proof of concept data center cooling system by Intel and SGI. As it boils off easily, it is used with a condensing loop running cold water.
3M produces FK-5-1-12 under the name Novec 1230.
