Overall log10Pow: In
the range 3.29 to 8.17
Partition coefficient: In
the range 1.93 x 103to 1.48 x 108
For 99.7 % of the test item (peaks 6 to 23), based on percentage area normalization:
Log10Pow: In
the range 4.62 to 8.17
Partition coefficient: In
the range 4.12 x 104to 1.48 x 108
The weighted average log10 Powwas 6.46.
Applicant's summary and conclusion
- Conclusions:
- The partition coefficient of the test item has been determined to be in the range 1.93 x 103 to 1.48 x 108, log10 Pow in the range 3.29 to 8.17. The weighted average log10 Pow was 6.46.
- Executive summary:
The determination was carried out using the HPLC Method designed to be compatible with Method A8 Partition Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 117 of the OECD Guidelines for Testing of Chemicals, 13 April 2004.
The test system consisted of a high performance liquid chromatograph (HPLC) with a suitable detector. A reverse phase HPLC column with a very low percentage of polar groups was used.
Conclusion
The partition coefficient of the test item has been determined to be in the range 1.93 x 103to 1.48 x 108, log10Pow in the range 3.29 to 8.17. The weighted average log10 Powwas 6.46.
