Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 HPLC estimation method based on soil-adsorption reference data was used for the determination of the adsorption coefficient (Koc) of the substance. The study was performed in accordance with OECD 121 and in compliance with GLP. The mobile phase was 55/45 (v/v) methanol/water and the wavelength of detection 210 nm. The stationary phase contained cyanopropyl chains chemically bonded to silica. Formamide was used as unretained substance. Duplicate injections of reference substances and test substance. The chromatogram of the test substance showed one test substance peak. The corresponding log Koc value was calculated from the regression line to be 4.07 (Koc= 1.2E04).
Key value for chemical safety assessment
- Koc at 20 °C:
- 12 000
Additional information
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.
