EC number: 470-270-6 | CAS number: -
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:
- 2007
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- Deviations:
- yes
- Remarks:
- see comments
- Principles of method if other than guideline:
- In the preliminary test, a good solubility in water and a very poor solubility in n-octanol were found indicating a partition coefficient below -2. Hence, a main test according to OECD 117 could not be applied. Therefore the partition coefficient was estimated using the solubility data in n-octanol from the pre-test and the water solubility from the pre-test and the water solubility from the main test.
- 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:
- ca. -3.7
- Temp.:
- 20 °C
- Remarks on result:
- other: The log Pow was calculated from the individual solubilities in n-octanol and in water, respectively.
- Conclusions:
- The log Pow was calculated from the individual solubilities in n-octanol and in water, respectively.
