Difluorodiphenyltrichloroethane (DFDT) is a chemical compound. Its composition is the same as that of theinsecticideDDT, except that two of DDT'schlorine atoms are replaced by twofluorine atoms.[1]
DFDT was developed as an insecticide by German scientists duringWorld War II. It is possible thatHoechst wanted to avoid license fees for DDT toSchering or the original developerJ. R. Geigy (the laterCiba-Geigy). It was documented by Allied military intelligence, but for Americans it remained in obscurity after the war.[1]
In 2019,New York University chemists reported that DFDT and a mono-fluorinated derivative, MFDT, might be a more effective insecticide than DDT, and might therefore be used to combatmalaria with less of an environmental impact.[1][2] A later study of DFDT found it to be encumbered by the sameresistance as DDT while being less effective inDrosophila melanogaster, and "unlikely to be a viable public health vector control insecticide".[3]
