- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7570 (Partition Coefficient, n-octanol / H2O, Estimation by Liquid Chromatography)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- HPLC method
- Partition coefficient type:
- octanol-water
- Analytical method:
- high-performance liquid chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- > 7.2
- pH:
- 7
- Remarks on result:
- other: The temperature was not reported
- Details on results:
- In the chromatogram of the test item solution, one peak with a retention time of 29.8 minutes was observed.
Under the same analytical conditions, the retention time of benzo[ghi]perylene (log Pow = 7.2)
was 18.6 minutes. Hence, it was concluded that the log Pow of substance is > 7.2 (Pow > 1.6x10(7)). - Conclusions:
- The partition coefficient (Pow) of 4,4'-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene) is > 1.6*10^7 at neutral pH and log Pow >7.2.
- Executive summary:
The partition coefficient (Pow) of 4,4'-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene) is > 1.6*10^7 at neutral pH and log Pow >7.2.
