Conclusions:
Interpretation of results: insoluble (< 0.1 mg/L)
The test substance has a water solubility of 17 µg/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 17 µg/L (23-24 °C).
