Additional information

Partition coefficient study for the test substance was conducted according to OECD Guideline 117 (HPLC method) under GLP. The test substance was found to have a Log10Pow value of 1.4.

In the study (Valvani, 1979), the log Pow of the test substance is determined as 1.48 at 25℃. This result was supported by EPA's tool "KOWWIN Program (v1.67)" where the Log Kow of the test substance was calculated as 1.71. In a further study (Inel, 1996), the log Pow of the test substance is calculated (using modelling) as 2.20, but the report could not be made available.
