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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
