Notes

1,5,9 cyclododecatriene
CDDT
Formula
C12H18

CDDT is used to produce cyclododecane, which is used in the production of dodecanedioic acid. Dodecanedioic acid can be used in dyes, solvents, adhesives, cleaning agents fertilisers,... .

CDDT has a high volatility, which causes it to have an aquatic half-life (by evaporation) of only 1,3 hours. In the atmosphere it will be degraded rapidly (in less than 30 minutes). As a consequence CDDT will be found mostly in soils, and very little in water, air or sediment. It is not considered to be biodegradable and has a low tendency to bioaccumulate.

Aquatic concentrations above 0,2 mg/l cause acute toxicity to fish, algae and invertebrates. A dose of 2,5 g/kg body weight is lethal to rats.

Considering CDDT it is only used as an intermediate in the production of other chemicals, its high volatility and degradability, it has only a minor potential aquatic exposure and thus poses only a minor risk to aquatic organisms[1].
