Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- ca. 3.3
- Temp.:
- 22 °C
- Remarks on result:
- other: pH not indicated
Any other information on results incl. tables
Solubility in water: 166 mg/L
Solubility in octanol: 314 000 mg/L
log P = log (conc in oct / conc in water) = 3.3
Applicant's summary and conclusion
- Conclusions:
- The comparison of measured solubilities in octanol and in water separately by spectrometry gives an extrapolated log Kow value for the substance of 3.3
