Remarks on result:
other: QSAR predicted value

KOWWIN predicted that the test substance has a log Kow of 2.57.

The calculated log Pow is 2.57 (EPI-Suite, EPA USA/KOWWIN v1.68).
Executive summary:

The calculated log Pow of the test substance is 2.57 (EPI-Suite, EPA USA / KOWWIN v1.68).

Description of key information
