Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The flask method was applied for the determination of the water solubility of V173520.

Based on the response of the anion of the substance, the water solubility of the test substance at 20°C was 263 g/l. Based on the response of the cation of the substance, the water solubility of the test substance at 20°C was 265 g/l. From this it could be concluded that the water solubility of the test substance is 264 g/l.

The pH of the aqueous samples was 2.7.
