Any other information on results incl. tables
Preliminary test:
Different amounts of the test item were suspended in deionised water and the respective mixture was stirred 2h at room temperature. The results are summarized below. As they were above 0.01 g/L, the flask method was selected.

The test solutions were slightly hazy; this likely results in a slight overestimation of the water solubility.
The pH value of the sample solution was 4.44 (4.41, 4.42) after 24 (48, 72) hours of incubation.
