Preliminary Visual Estimation of the Water Solubility
Appearance of the test mixtures in the preliminary test:
| Amount of the test item in mg | Total volume in ml | Appearance of mixture |
| 100 | 1.0 | Undissolved |
| 100 | 2.5 | Dissolved |
| 100 | 5.0 | Dissolved |
The preliminary visual experiments showed that the water solubility of the test item is about 40 g/l.
