Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
One experimental study is available to assess the adsorption coefficient on soil and sewage sludge of the registered substance. This study was performed according to OECD Guideline 121 and EU Method C.19 with GLP compliance. The test utilized a high performance liquid chromatograph. Eleven reference items with different retention times were used to produce the calibration curve. They were chosen in relation with the expected retention time of the test item. For each reference item, two determinations were performed. The capacity factor (k) was calculated from the retention time of sodium nitrate (dead time) and the retention time of the respective reference item. A calibration function (log Koc versus log k, linear fit) was determined based on literature values of Koc for the reference items. All validity criteria were fulfilled. The substance was determined to have a log Koc value of 3.05 (equivalent to Koc = 1122). This value is the mean of two independent measurements and indicates that the registered substance is low mobile in soils (according toP.J. McCall et al., 1980).
Additional information
Although not requested under REACH Annex VII, the adsorption study was performed to comply with worldwide regulations.
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.
