Results and discussion

Partition coefficient
Key result
Type:
Pow
Partition coefficient:
ca. 27.2
Temp.:
20 °C
pH:
ca. 7
Details on results:
Abs in octan-1-ol 0.172854@ 330nm (20 fold dilution required to get the abs in range) giving a concentration of 3.45
Abs in water 0.126836@266nm

3.45/0.126836 = 27.2

Applicant's summary and conclusion

Conclusions:
The Pow was experimentally determined to be 27.2 in a lab with a constant temperature of 20°C.
Executive summary:

The Pow was experimentally determined to be 27.2 in a lab with a constant temperature of 20°C.
