Description of key information

Cu(II)IDHA_OECD 107: logPow = - 3.09 ± 0.27 at 23 °C

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
23 °C

Additional information

The log Pow value for the substance CuIDHA was determined according to OECD Guideline 107 (Stegient-Nowicka, 2011). The N-octanol/water coefficient has been measured in the Shake Flask method, which consists of dissolving some of the solute in question in a volume of octanol and water, then measuring the concentration of the solute in each solvent. The spectrophotometric method was used to determinate the concentration of the test item in both phases. As final result, the log Pow value is reported as -3.09 +/- 0.27 at 23 °C.
