title: A new synthesis of tetrachlorofluorodibenzo-p-dioxin.
abstract: The 1,2,3,4-tetrachloro-7-fluorodibenzo-p-dioxin has been synthesized via condensation of 4-fluorocatechol and pentachloronitrobenzene. This compound could be used as an internal standard for the analysis of 2,3,7,8-tetrachlorodibenzo-p-dioxin by chromatographic methods.
