Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The flask method was chosen for the determination of the water solubility of ASA404 C7. The water solubility of the test substance at 19.9 ± 0.6°C
was 18.0 mg/l. The pH of the aqueous sample after 72 hours stirring was 5.2.
