Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Calculated log Pow= 6.24 at 25°C
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 6.24
- at the temperature of:
- 25 °C
Additional information
The preliminary experiment carried out by the flask shaking method and yielded a log P > 5.26 This value shows that the expected P lies outside the range of the flask shaking method and must be estimated by the calculation method.
The calculation methods are described and discussed in the ANNEX of the Testing Guideline 117. They are all based on the formal fragmentation of the molecule into suitable substructures for which reliable log P increments are known.
The log Pow was calculated using Computer program CLOGP Release 3.42, Medicinal Chemistry Project, Pomona College, Claremont, Calif. 9171 which yielded a value of 7.2 (1992).
In the mean time (2017) there is improvement of the estimation software. Thus, the log Pow value has been reviewed and calculated using the common KOWWIN (v1.68) module of software EPI Suite v.4.11. The substance is within the applicability domain of the model therefore the result given is considered reliable.
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.
