Applicant's summary and conclusion
- Conclusions:
- The partition coefficient of the test substance, 3,3,4,4,4,4-pentafluorobut-1-ene was predicted to be 1.15 x 10^3, log10 Pow 3.06.
- Executive summary:
The partition coefficient between n-octanol and water for the test substance, 3,3,4,4,4,4 -pentafluorobut-1 -ene, was calculated using KOWWIN v 1.68 (U.S. EPA) based on information on the test substance provided by the Sponsor. The structure of the test substance was entered into the software and the results were produced.
The partition coefficient (Pow) was calculated using the following equation: Pow = 10^log10 Pow.
The partition coefficient of the test substance, 3,3,4,4,4,4-pentafluorobut-1-ene was predicted to be 1.15 x 10^3, log10 Pow 3.06.
