- octanol-water
- Analytical method:
- high-performance liquid chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- ca. 3.7
- Temp.:
- 20 °C
- Remarks on result:

- Conclusions:
- The determination of log Pow by High Performance Liquid Chromatography (EU Method A.8) results in two log Pow
LogP=3.4 and LogP=3.7 - Executive summary:
The determination of log Pow was performed by High Performance Liquid Chromatography (EU Method A.8)
The log Pow of the substance was interpolated from a regression line obtained from nine reference substances. Two partition coefficients (n-octanol/water) were associated with the test substance and determined to be 2.5 * 10E3 (log Pow = 3.4) and 5.0 * 10E3 (log Pow = 3.7) at 20.0 ± 0.50 C. The lower value represents probably a decomposition product, the higher the test substance.
