properties

Trifluoroiodomethane is a colorless, non-flammable, light-sensitive gas.

use

Trifluoroiodomethane provides free CF ₃ radicals when heated and when irradiated with UV light and is therefore suitable for the synthesis of numerous compounds of the CF ₃ (CF ₂ ) _n -X type as well as organometallic and organometalloid compounds. It has an ozone depletion potential of 0.01 to 0.02.
