Substance Name: DDT [BSI:ISO]
RN: 50-29-3
UNII: CIW5S16655
InChIKey: YVGGHNCTFXOJCH-UHFFFAOYSA-N

Note

  • A polychlorinated pesticide that is resistant to destruction by light and oxidation. Its unusual stability has resulted in difficulties in residue removal from water, soil, and foodstuffs. This substance may reasonably be anticipated to be a carcinogen: Fourth Annual Report on Carcinogens (NTP-85-002, 1985). (From Merck Index, 11th ed)
