- Conclusions:
- The n-octanol solubility of the test item is 159.0 ± 0.493 g/L (standard deviation).
- Executive summary:
The n-octanol solubility of the test item was determined according to OECD Guideline 105 – Flask method. n-Octanol was used instead of water. The n-octanol solubility of the test item is 159.0 ± 0.493 g/L (standard deviation). The external standard method was used. The n-octanol solubility was determined at 20 °C.
