Description of key information

Literature references state partition coefficients between log Pow = 1.66 - 1.98.

Key value for chemical safety assessment

Log Kow (Log Pow):
1.98
at the temperature of:
20 °C

Additional information

Several peer reviewed literature sources are available stating n-octanol / water partition coefficients log Pow from 1.66 to 1.98.

The lowest value of 1.66 is cited in a review article but without reference to the original source. All other values are in the range between 1.91 and 1.98. The best choice seems to be the log Pow determined by Lacko (1981) as the the experimental conditions are similar to OECD guideline No. 107 (shake flask method).
