Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The test substance is slightly soluble. Water solubility is estimated to be < 0.9 mg/L at 20 deg. C
Executive summary:

The water solubility was determined by the shake flask method. In a preliminary test, it was found that suspended, water insoluble material could not be removed either by filtration or centrifugation to provide a suitable sample for analysis. As a result, the water solubility was visually estimated. At a nominal concentration of 0.9 mg/L, undissolved test material was observed indicating the water solubility of the test substance is < 0.9 mg/L at 20 deg. C.
