Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The water solubility is 3.5 µg/L at 24°C (ambient temperature)
Executive summary:

The water solubility of the test item was determined according to the analytical method that was agreed upon at the “Analytical Experts Meeting” of ETAD (Basel) on January 12, 2005 and was found to be 3.5 µg / L at 24°C (ambient temperature)
