20 °C

Additional information

The key studies of the year 1997 and 2000 show comparable values for the water solubility at pH 7,5. The up-to-date value of 1.85 g/L is taken for the CSA.

SMBP, 1997:
2.24 g/L at 20 °C, ca. pH 7.5   
19.5 ± 0.5°C

ADK STAB NA-11, 2000
1.85 g/L at 20 °C, ca. pH 7.5    
19.5 ± 0.5°C

BC-300, 2001
21.9 mg/L at pH 5, and 172 mg/L at pH 9.    30°C
