What is methoxy-nonafluorobutane?

Methoxy-nonafluorobutane is a colorless, odorless, and non-flammable gas. Its chemical formula is C4F9OCH3, and its molecular weight is 316.05 g/mol. Methoxy-nonafluorobutane is a fluorinated ether and is sometimes referred to as 1,1,2,2,3,3,4,4,4-nonafluoro-4-methoxybutane.

Methoxy-nonafluorobutane finds its application as a solvent, blowing agent, refrigerant, and as an electrical insulating gas. It is also used in the semiconductor industry as an etching gas or plasma source.

Methoxy-nonafluorobutane is known to have low toxicity and does not pose any threat to the environment. It is generally preferred over other fluorinated gases due to its lower global warming potential. The gas is generally shipped and handled under pressure in steel cylinders.
