Notes

1,5,9 cyclododecatriene
CDDT
Formula
C12H18

CDDT is used to produce cyclododecane, which is used in the production of dodecanedioic acid.

It 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 however is considered not to be biodegradable. It has a low tendency towards bioaccumulation.

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]
