Results and discussion

Water solubility
Key result
Water solubility:
< 0.1 mg/L
Conc. based on:
test mat. (dissolved fraction)
Temp.:
24 °C
Remarks on result:
other: Concentration in filtrate as determined by colorimetry

Applicant's summary and conclusion

Conclusions:
The substance is known to be very poorly soluble so a specific colorimetric method was employed. It demonstrated that a suspension in water at 24°C, agitated and filtered, contains less than 0.1 mg/L of the substance (0.063 mg/L being the maximal measured value out of 4 assays).
