Description of key information
The adsorption coefficient was assessed according to EU Method C19 and OECD Test Guideline 121 using the HPLC screening method. The adsorption coefficient was 9.46E+04 to greater than 4.27E+05, log10Koc in the range 4.98 to greater than 5.63.
Key value for chemical safety assessment
- Koc at 20 °C:
- 427 000
Additional information
The adsorption coefficient was assessed according to Method C19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001 using the HPLC screening method. The test was performed at approximately neutral pH with the test item in a non-ionized form. The chromatography of the test item showed five peaks with well-defined and reproducible retention times.
The adsorption coefficient was 9.46 x 104to greater than 4.27 x 105, log10Koc in the range 4.98 to greater than 5.63. These values indicate that the test item will be immobile in the environment.
[LogKoc: 5.63]
