Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2002
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- HPLC method
- Partition coefficient type:
- octanol-water
- Analytical method:
- high-performance liquid chromatography
- Type:
- log Pow
- Partition coefficient:
- 2.18
- Temp.:
- 25 °C
- Remarks on result:
- other: 95 % confidence limits 1.96 - 2.39
- Conclusions:
- The partition coefficient (log Pow) was determined to be 2.18 at 25°C and pH 7.
- Executive summary:
The n-octanol/water partition coefficient (log Pow) was determined according to EU Testing Guideline A.8 (HPLC method based on OECD guideline no. 117) to be 2.18 (95 % confidence limits 1.96 -2.39) at 25 °C, which indicates no lipophilicity. The method is based on the correlation of the reversed phase retention data of the test compound with those of reference compounds with known log Pow values.
