Key result
Type:
log Pow
Partition coefficient:
0.3
Temp.:
40 °C
Remarks on result:
other: The pH was not reported.

Triplicate HPLC analyses yielded a mean log Pow of 0.3 ± 0.0.

Conclusions:
A log Kow value of 0.3 ± 0.0 at 40°C was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.
