Description of key information
The determination of adsorption coeffcient of the test substance was carried out using the HPLC screening method, designed to be compatible with EU Method C.19 and OECD Guideline 121, in compliance with GLP. The test system utilized a high performance liquid chromatograph. A commercially available cyanopropyl reverse phase HPLC column containing lipophilic and polar moieties was used. As the test item has estimated (ACD/Labs I-Lab 2.0) pKa’s of approximately 5.2 and 10.4 (where the two OH groups are opposite each other, and approximately 4.3 and 10.3 (where the two OH groups are adjacent to each other), it was considered appropriate to perform testing at pH 5.5 and pH 7. The adsorption coefficient (Koc) of the test item at pH 7 has been determined to be in the range 8.03 x 103to greater than 4.27 x 105, log10 Koc in the range 3.91 to greater than 5.63. These values indicate that the test item will be immobile at pH 7. The adsorption coefficient (Koc) of the test item at pH 5.5 has been determined to be greater than 4.27x 105, log10 Koc greater than 5.63. These values indicate that the test item will be immobile at pH 5.5.
