Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
OECD Guideline 121, EU Method C.19, GLP, key study, validity 1:
Koc = 6100; log Koc = 3.78.
immobile in soils (according to P.J. McCall et al., 1981).
Key value for chemical safety assessment
- Koc at 20 °C:
- 6 100
Additional information
To assess the adsorption potential of the registered substance, one key experimental study is available.
This study (WIL Research Europe V.B., 2015) was performed on the registered substance according to OECD Guideline 121 and EU Method C.19 (HPLC screening method) under GLP. According to this study, the adsorption coefficient of the registered substance was determined at 6100, corresponding to a log Koc at 3.78, at neutral pH. The result indicates that the substance is environmentally immobile in soils (according to P.J. McCall et al., 19811).

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.
