*) exp. A-C in a solution 1 mL centrifugate to 10 mL water (the centrifugate was high viscous and only 2 mL, not enough for using a pH-meter); exp. D without solution
Example for calculation, experiment A: ca. 0.1-50/10-50
WS = 364.826 mg/L * 50 mL * 50.14 g / (10 mL * 0.11764 g * 1000 mL/L) = 777.46 g/L.
Average (experiments A-C): 793.4 g/L, standard deviation 13.3 g/L, relative standard deviation 2%
Corrected with the purity of the test substance 97.1%: 770 g/L, SD 17 g/L, RSD 2%.
Description of key information
770 g/L at 20 °C, pH = 5
Key value for chemical safety assessment
- Water solubility:
- 770 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of the substance was determined according to OECD Guideline 105 and EU Method A.6. The substance is very well soluble in water.
