- Key result
- Type:
- log Pow
- Partition coefficient:
- < 0
- Temp.:
- 20 °C
- pH:
- 7.09
- Remarks on result:
- not determinable because of methodological limitations
- Details on results:
- The log Pow values were below the limit of the method.
- Conclusions:
- The log Pow values are below the limit of the method (log Pow < 0)
- Executive summary:
Determination of the log Pow was performed in accordance with OECD Guideline 117 and EC Method A8; HPLC Method.
The anlysis was performed on an analytical column packed with a solid phase containing long hydrocarbon chains chemically bound onto silica. A mixture of 60% methanol to 40% 0.01 M phopshate buffer (pH 7.09) was used as the mobile phase and the column temperature was 20 °C.
The log Pow values are below the limit of the method (log Pow < 0). Repeatability of the method could not be determined.
