Water solubility:
29.4 mg/L
20 °C
>= 7.7 - <= 7.8
Details on results:
The results show that the solubility in ultrapure water is 29.4 mg/L

The pH values of the solutions in ultrapure water were ph 7.7 to 7.8 at the 3 sampling times.

The chromatograms of the test substance show one peak at an average retention time of ~9.3 minutes. Additional peaks at retention times of ~11.5 mins and ~14.5 mins (after 72 hr and 96 hr) were observed on the chromatograms of extracts. This indicates that the test material is not stable under the test conditions.

The data are given below:

Concentration (g/L)

Contact time (hr)

Ultrapure water, sample 1 28.94 29.4 29.39 29.4
Ultrapure water, sample 2 29.36 29.46 45.39
The water solubility of the test substance was determined to be 29.4 mg/L in ultrapure water.
