flask method

Key result

Water solubility:

25 µg/L

Conc. based on:

test mat. (total fraction)

Incubation duration:

72 h

Temp.:

23 °C

Remarks on result:

other: no data on pH

Details on results:

3 independent vials from each solubility test were injected and measured. Each result given in the table below is the average of these 3 measurements.
The solubility in n-octanol and in water is 25 µg/L.

Conclusions:

The water solubility of test substance was determined to be 25 µg/L at 23°C.
