Results and discussion

Partition coefficient
Type:
log Pow
Partition coefficient:
ca. 3.36
Temp.:
24 °C
pH:
2
Details on results:
The results showed that the substance displayed a weighted average log Pow of 3.36.

The error in the measurements was estimated using the relative percent difference (RPD) of the two independent preparations analyzed in these experiments. The difference between the two preparations was 0.07 log units, corresponding to 21 % RSD.
