Trifluoroacetaldehyde, trifluoroethanal, or fluoral, 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. It is highly electrophilic and fluoral forms a hydrate CF₃CH(OH)₂ upon contact with water like other halogenated acetaldehydes. 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.
