Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The test substance has a water solubility of 5.4 µg/L.
Executive summary:

The water solubility was determined by UV-Vis analysis of the dissolved test substance amount in 30 mL water according to the method that was agreed upon at the Analytical Experts Meeting of ETAD (Basel) on January 12, 2005.

The test substance has a water solubility of 5.4 µg/L (23 -24 °C).
