+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,... .
-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 and has a low tendency to [[bioaccumulation|bioaccumulate]].
