Applicant's summary and conclusion

Conclusions:

Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of the test item has been determined to be less than or equal to 1.91 x 10-3 g/l of solution at 20.0 ± 0.5°C.

Executive summary:

Method

The determination was carried out using the flask method designed to be compatible with Method A6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Conclusion

The water solubility of the test item has been determined to be less than or equal to 1.91 x 10^-3g/l of solution at 20.0 ± 0.5°C.
