Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- < 1.5
- Temp.:
- 20 °C
- pH:
- ca. 4.97
Applicant's summary and conclusion
- Conclusions:
- log Kow < 1.5 @ 20 C
- Executive summary:
The partition coefficient of compound 202723 was performed with reference to OECD Guideline 117 by dissolving the test substance in methanol before performing HPLC analysis. It was determined that compound 202723 was unretained by the chromatographic system and therefore the log Pow was determined as <1.5.
