Fluoral
Fluoral
Chemical compound
Trifluoroacetaldehyde, trifluoroethanal, or fluoral,[2] is a fluorinated derivative of acetaldehyde with the formula CF3CHO. It is a gas at room temperature. Fluoral is used to introduce trifluoromethyl groups into organic compounds.[2][3] It is highly electrophilic and fluoral forms a hydrate CF3CH(OH)2 upon contact with water like other halogenated acetaldehydes.[4] It is commonly used in form of ethyl hemiacetal (1-ethoxy-2,2,2-trifluoroethanol, CF3CH(OCH2CH3)(OH)) due to the aldehyde's high reactivity, including the tendency to polymerise.[5]
