Description of key information

0.106 g/L at 20 °C and pH 2

57.5 g/L at 20 °C and pH 5.7

64.2 g/L at 20 °C and pH 5.9

(OECD Guideline 105, Flask method)

The key value for chemical safety assessment refers to pH 5.9.

The pH-value of the saturated test substance solution in water is 3.4. Therefore accurate pH-values at 7 and 9 could not be obtained in the test, even if high concentrated buffers are used.
