Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility ot the substance was determined as 14 mg/L at 23°C.
Executive summary:

The water solubility of the substance was determined 3 times according to the method developed by the ETAD at 23°C. The average of the results was 14 mg/L.
