Description of key information

The measured log Koc = 3.744 indicates that the substance is slightly mobile in soil and sediment according to the classification scheme of McCall et al. (1981).

Key value for chemical safety assessment

Koc at 20 °C:
5 546

Additional information

The log KOC value of the test substance was determined in an adsorption/screening test using the HPLC method according to OECD Guideline 121. A calibration curve correlating log KOC and the retention time was generated using 6 reference items with different retention times. Three measurements were performed with each reference item and the test substance sample. For each reference item, the capacity factor k’ was calculated from the retention time of sodium nitrate and the retention time of the respective reference item. The retention time of the test substance was found to be 8.074 min.The log KOC of the test substance was then determined as 3.744±0.017 (range: 3.729-3.762) at 25°C.
