Fluoroethane (also known as ethyl fluoride) is a hydrofluorocarbon with the chemical formula C2H5F). It is a volatile derivative of ethane. It appears as a colourless, odorless flammable gas at room temperature.3 Fluoroethane can also cause asphyxiation by the displacement of oxygen in air.4

Reactivity

Fluoroethane is incompatible with most strong reducing agents and oxidizers, and may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.5 It is part of the wider class of substances known as fluorinated organic compounds.6
