| IUPAC name: | (1R,4S,4aS,5S,8R,8aR)-1,2,3,4,10,10-hexachloro-1,4,4a,5,8,8a-hexahydro-1,4:5,8-dimethanonaphthalene |
| CAS name: | (1R,4S,4aS,5S,8R,8aR)-rel-1,2,3,4,10,10-hexachloro-1,4,4a,5,8,8a-hexahydro-1,4:5,8-dimethanonaphthalene |
| CAS Reg. No.: | 309-00-2 |
| Formula: | C12H8Cl6 |
| Activity: | insecticides (chlorinated cyclodiene) |
| Notes: | The common name “HHDN” was also formerly approved by ISO for this substance, but was withdrawn in 2020. The 5R,8S isomer has the ISO common name isodrin [465-73-6]. The names dieldrin and aldrin are derived from the Diels-Alder chemical reaction, and their pronunciation should reflect the names of the German chemists Dr O. Diels and Dr K. Alder. |
