- Specific details on test material used for the study:
- - CAS RN: 71902-20-0
- Physical State/Appearance: Yellow liquid
- Purity: > 95% - Analytical method:
- other: liquid chromatography / mass spectrometry
- Key result
- Type:
- log Pow
- Partition coefficient:
- 2.4
- Remarks on result:
- other: calculation
- Type:
- log Pow
- Partition coefficient:
- 1.53
- Temp.:
- 22 °C
- pH:
- >= 7.35 - <= 7.69
- Conclusions:
- Under the conditions of the study, the partition coefficient (LogPow) of the test material has been determined to be 2.4.
- Executive summary:
Under the conditions of the study, the partition coefficient (LogPow) of the test material has been determined to be 2.4 via calculation method, using the octanol solubility assessment and 1.53 using the shake flask method.
The difference between the two LogPowresults indicated that surface activity may have impacted the shake flask results to some extent and the estimated LogPowhas been reported.
