- Conclusions:
- The log Pow was determined to be 3.55 at 23 °C, pH 7.
- Executive summary:
The partition coefficient of the test item was determined according to OECD TG 107. The log Pow was determined to be 3.55 at 23 °C, pH 7.
Reference
Individual study results are attached.
The test item was quantified by integrating over the whole peak area in the chromatograms, consisting of one main signal and two minor signals. The chromatograms obtained for the 1 -octanol phases show all three signals. In the chromatograms obtained for the aqueous buffer phases, only the earliest eluting signal is observed.
Calibration curve and selected chromatograms are attached.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
