Perfluoro(2-methyl-3-pentanone)

Perfluoro(2-methyl-3-pentanone) (CAS 756-13-8), commercially known as Novec 649 and classified under the fluid designation FK-5-1-12, is a fully fluorinated ketone solvent used in precision cleaning and fire suppression.

Where is Perfluoro(2-methyl-3-pentanone) used?

• Electronics manufacturing: cleaning and defluxing solvent for PCBs, semiconductor components, and precision assemblies
• Industrial cleaning: degreasing metal parts and optical components where hydrocarbon or aqueous systems are unsuitable
• Heat transfer fluid and dielectric coolant in immersion cooling systems for data center hardware
• In fire suppression, FK-5-1-12 is the active agent in clean agent systems that protect sensitive equipment without conductive or corrosive residues.

Good to know: Its low global warming potential relative to legacy fluorinated solvents makes it an alternative to older halon and HFC-based chemistries.
