Results and discussion

Water solubility
Water solubility:
> 1 000 g/L
Temp.:
20 °C
pH:
3
Details on results:
Pre-test results show that the solubility of the test item is about 1~10 g/L, but the test item
can be continuously dissolved during the flask shaking process. The three determination results
are 1517.1 g/L, 1515.6 g/L, and 1504.4 g/L, respectively. It is greater than 1000 g/L, therefore,
we report >1000 g/L as the test result, and also indicate pH=3.0.

Applicant's summary and conclusion

Conclusions:
Pre-test result: 1~10 g/L
Formal test result: >1000 g/L(20℃,pH=3.0)
