Reference
Twenty five compounds were observed in the LC-MS
chromatograms of the test substance solution. With all test
substance related compounds it was found that its retention
time was higher than the retention time of 2,4-DDT with a
log Pow of 6.5.
Description of key information
The partition coefficient was determined using the HPLC method and the study was performed according to OECD Guideline 117/EU method A.8 and GLP principles.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 6.5
- at the temperature of:
- 22 °C
Additional information
Twenty five test substance related compounds were observed. The log Pow value was > 6.5 for all test substance related compounds.
