Description of key information

The partition coefficient of 4-Hydroxy TEMPO was estimated to 0.56 at 25 °C.

Key value for chemical safety assessment

Log Kow (Log Pow):
0.56
at the temperature of:
25 °C

Additional information

The result was determined by QSAR estimation with the programme EPIWIN using KOWWIN v.1.65 that is recommended in the REACH Guidance on information requirements and chemical safety assessment, Chapter R.7.1.8.3, Table R.7.1 -24, thus the calculated value is reliable with restrictions. The value for the partition coefficient was calculated to be 0.56.
