Details on results:
The water solubility determined by the flask stirring method at the temperature of 21ºC is: 
15.685 ± 3.86 g/l
n=11, CV= 2.461%

Any other information on results incl. tables

The pH at the saturation concentration ranged from 2.55 to 2.63

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L) 15.685 ± 3.86 g/l
The water solubility of A-164220.0 was evaluated to be 15.685 ± 3.86 g/l (n=11) @ 21°C
Executive summary:

Equilibrium saturation occured verey quickly. At the 3 hr sampling time the saturation value found did not differ significantly from the values recorded at the successive times.

It was also observed that prolonged stirring did not increase the saturation equilibrium and that the test substance did not decompose on staying longer in water.
