- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- HPLC method
- Key result
- Type:
- log Pow
- Partition coefficient:
- < 0
- Remarks on result:
- other: Temp.: Room temperature
- Remarks:
- pH: not applicable
- Conclusions:
- The partition coefficient of the test item Clevios K Primer W8 (1,10-Decanediamine, 4-methylbenzenesulfonate (1:2)), is determined to be: log Pow < 0
- Executive summary:
Calculation of the partition coefficient (Method: SOP 00187 Version 3):
The result of the pretests is a higher solbulity of the test item in demineralized water than in 1-octanol. Therefore, based on the assumption that in the formula of the partition coefficient the concentration in each phase can be substituted by approximation with the solubility in each solvent, the partition coefficient can be estimated.
With Pow≈Sol1-octanol / Solwater
and Sol1-octanol < Solwater
it is: Pow < 1 and log(Pow) < 0
Result: The partition coefficient of the test item Clevios K Primer W8 (1,10-Decanediamine, 4-methylbenzenesulfonate (1:2), is determined to be: log Pow < 0
