Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance has a Koc of 1445 L/kg and a log Koc of 3.16 using OECD TG 121.
Key value for chemical safety assessment
- Koc at 20 °C:
- 1 445
Additional information
The adsorption coefficient (Koc) of the test substance was determined in a HPLC screening test according to EU Method C.19 and in compliance with GLP criteria (Huntingdon, 2005). Solutions of reference substances with known log Koc values based on soil adsorption data and the test substance were analysed by HPLC using a Hypersil H5CPS column. The log k’ values of reference substances were plotted against the known log Koc values. The log Koc value for the test substance was calculated by substituting its mean log k’ in the calibration curve. Under the conditions of the test, the log Koc of the test substance was determined to be 3.16, which is equivalent to a Koc value of 1445 L/kg.
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.
