Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The test substance has a water solubility of 0.19 mg/L.
Executive summary:

The water solubility was determined by UV-Vis analysis of the dissolved test substance amount in 30 mL water.

The test substance has a water solubility of 0.19 mg/L (22-23 °C).
