Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Estimated based on solubility ratio:
Log Pow= >5 at 20°C
Key value for chemical safety assessment
Additional information
Due to the fact of the differences in the sobulity of the test item in water (see endpoint 4.8) and in n-octanol the determination of the log Pow corresponding to the OECD Guideline 107 (shake flask method) is not feasible. Because the test item cannot be chromatographed under the prescribed conditions the HPLC-method (OECD Guideline 117) is also not feasible.
Due to this, the log Pow can only be estimated from the single solubilities of the test item in water and in n-octanol.
Since a generally valid water solubility of the test item cannot be determined, because the water solubility depends on the sample size applied as well as on the determination method, it is also not possible to estimate a generally valid log Pow value from the single solubilities in n-octanol and in water.
It can be suggested that the partition coefficient of test substance was estimated to be log Pow= >5 at 20°C.
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.
