Description of key information
log Koc was 1.30 for the substance (Koc= 20) and < 1.26 for the impurity (Koc < 18).
Key value for chemical safety assessment
- Koc at 20 °C:
- 20
Additional information
The HPLC method was performed at pH 7 as the test substance is a salt. The HPLC method using soil-adsorption-reference data was applied for the determination of the adsorption coefficient (Koc) of S-10793. The mobile phase was 30/70 (v/v) methanol/phosphate buffer pH 7. The column temperature was 35°C. In the HPLC chromatogram of the test solution, one major peak (99.6% peak area) and one small impurity peak (0.4% peak area) were observed. log Koc was 1.30 for the substance (Koc= 20) and < 1.26 for the impurity (Koc < 18). The study was performed in accordance with EC C.9 and OECD 121 and according to the principles of GLP.
[LogKoc: 1.3]
