Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
A number of measured values are available (values shown above are measured unless otherwise stated). These fall generally within a consistent and narrow range. The key value selected is a known measured value. This value also falls towards the lower end of the range of values availble (0.74 - 1.4), however, most data is in the range 0.74 to 0.83. Based on the structure of this substance, the partition co-efficient is not likely to be sensitive within the normal range of environmental pHs.
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.
