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:

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.

Description of key information
