Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- > 6.5
- Temp.:
- 22 °C
- pH:
- 7
- Details on results:
- In the chromatogram of the test substance solution no test substance peak was observed during isocratic elution with 75/25 (v/v) methanol/water. Yet, one test substance peak was observed at 16.2 minutes which is during the column rinse, i.e. under gradient conditions. Under isocratic conditions the retention time of 2,4-DDT (log Pow = 6.5) was 0.50 minutes. Hence, it was concluded that the log Pow of test substance was > 6.5 (Pow > 3.2 x 10^6).
Impurities with a peak area percentage of > 1% of the total peak area were not observed.
Any other information on results incl. tables
Calculation of the Pow
The calculation of the log Pow value of a modified structure (i.e. the Cu2+ was substituted by a carbon atom and the C15 chains were shortened to C7) by aid of the Rekker-calculation method resulted in a theoretical log Pow value of 33.72.
Calculation of the pKa
No pKa values were calculated for acidic and basic groups in the modified molecular structure of the test substance in the logarithm range of 1 – 14.
Applicant's summary and conclusion
- Conclusions:
- The logPow value of the test substance is > 6.5
