Qualifier:
according to
Guideline:
OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
GLP compliance:
no
Type of method:
HPLC method
Partition coefficient type:
octanol-water
Analytical method:
high-performance liquid chromatography
Type:

Temp.:
20 °C
pH:
ca. 6.5

It should be pointed out that DDT is the one with the largest lg Powvalue we can find from the references. The retention time of the sample achieved from the test was larger than DDT, however the lg Powvalue achieved from the linear fitting was smaller than DDT, the deviation equal to 0.3, which meet the accuracy requirement (±0.5 lg unit).

Conclusions:
The final result is lg Pow=5.9 (20°C, pH=6.5).
