Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The log Pow of the substance was determined to be 0.22 at 25 °C.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.22
- at the temperature of:
- 25 °C
Additional information
Data were taken from a scientifically acceptable study with detailed documentation. Different QSAR calculation give results in the same range. The log Pow was measured according to BASF standard method using shake-flask as type of the method. The test substance was monitored in both equilibrium phases by titrimetric determination. The mean value of three determinations is: log Pow = 0.22 at 25 °C and pH 11.3 - 11.6 (BASF AG, 1989). SPARC calculation resulted in a log Pow of -1.89, -1.88, -1.35 at pH 5, 7 and 9 resp. EpiWIN calculation resulted in a log Pow of 0.7 at 25°C (uncharged molecule). According to Hansch et al (HSDB database) a log Pow of 0.46 was found at 25°C at pH=13.
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.
