Description of key information

The OECD 121 study could not be conducted due to technical problems with the HPLC method. QSAR estimation was used to estimate the Koc of all constituent structures using both the MCI and log Kow methods, Weighted average values for log Koc using the MCI method is 9.60 - 9.95 and using the log Kow method is 8.43 - 8.66. The lowest value of 8.43 for log Koc was used in PNEC derivation in soil and sediments, as this is the most conservative value, leading to the lowest PNEC values.

Key value for chemical safety assessment

Koc at 20 °C:
269 153.48
