Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
Executive summary:

The water solubility was determined according to OECD TG 105. After a preliminary test, the column elution method was chosen and yielded a water solubility of 0.03 mg/L at 20 °C.
