Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- May 2012 to November 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient - Shake Flask Method)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Partition coefficient type:
- octanol-water
- Analytical method:
- gas chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- 2.86
- Temp.:
- 20.4 °C
- pH:
- 5.2
- Conclusions:
- The partition coefficient of the test item has been determined to be 723 at 20.4 +/- 0.5 degrees Celsius, Log Pow iof 2.86.
- Executive summary:
The determination of partition coefficient was performed using the shake-flask method. This was due to the expected partition coefficient obtained in the prelimnary assessment. The n-octanol saturated water was pH unadjusted as the test item contained no dissociating groups within the environmentally relevant pH range.
