Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 partition coefficient (log Pow) was 1.2 (100 area % of the test item) at 40 °C and pH 6.2 estimated by HPLC method according to
OECD guideline 117 (Currenta, 2009).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 1.2
- at the temperature of:
- 40 °C
Additional information
The HPLC method enables partition coefficients to be estimated in the log Pow range between 0 and 6. This method, however, is not applicable to strong acids and bases, metal complexes, substances which react with the eluent, or surface-active agents. Measurements should be made on ionisable substances in their non-ionized from (free acid or free base), using only an appropriate buffer with a pH below the pK for a free acid or above the pK for a free base. The pKa value is 12.92 ± 0.20 (calculated with the software ACD/pKa v 7.0 at a simplified structure of the test item). Therefore the undissociated form (protonated form) exists at a pH value < 12.
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.
