Description of key information

The weighted mean Log Kow based on the two resolved peaks and two broad peaks was 10.7 ± 0.0683.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
40 °C

Additional information

Under the chromatographic conditions specified, the test substance eluted as two broad and two

resolved peaks. The partition coefficients (Log KOW) for the test substance were calculated as 3.04; 4.86

to (6.69), with a value of 5.32 at the maximum peak height; (7.44); and (11.0) to (11.4), with a value of

(11.2) at maximum peak height. Values in parentheses are extrapolated values. The weighted mean Log

Kow, based on the two resolved peaks (peaks 1 and 3) and two broad peaks (peaks 2 and 4), was
