- Partition coefficient:
- 4.39
- Temp.:
- 25 °C
- Remarks on result:
- other: High concentration (3.66E-01 mM)
- Details on results:
- These values represent the mean of three values obtained for each concentration. The test substance was shown to preferentially remain in the n-octanol phase, with little partitioning into the aqueous phase. Based solely on these relatively high Kow values, i.e., greater than 104, the test substance would be expected to sorb to organic material in soil and sediment, in spite of the high Kow values, comparison with the properties of a closely related compound indicates a low potential for bioaccumulation in aquatic organisms.
- Conclusions:
- The n-octanol/water partition coeftacient of the test substance is 4.4 (log Pow).
