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:
- 20 - 26 March, 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient)
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7570 (Partition Coefficient, n-octanol / H2O, Estimation by Liquid Chromatography)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- HPLC method
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- - Name of test material (as cited in study report): Isobutavan
- Physical state: colourless to pale yellow liquid
- Lot/batch No.: SC00003539
- Expiration date of the lot/batch: November 26, 2013 - Analytical method:
- high-performance liquid chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- 2
- Temp.:
- 35 °C
- pH:
- 7
- Remarks on result:
- other: 35°C = column temperature. However, the logKow value can be considered to represent the value at an unspecified, probably ambient temperature as log Kow of the test and reference substances are assumed to vary with temperature in the same way.
- Details on results:
- Testing was performed at 35°C (column temperature), however the values can be considered to represent the values at an unspecified, probably ambient temperature since no mention is made in the guidelines of the temperature at which the tabulated reference substances log Kow values were determined. Partition coefficients of the test and reference substances are assumed to vary with temperature in the same way.
- Conclusions:
- The partition coefficients n-octanol/water of Isobutavan is log Pow = 2.0.
- Executive summary:
The partition coefficients n-octanol/water of Isobutavan is log Pow = 2.0 according to the OECD guideline No. 117.
