Description of key information

 The substance is miscible in all proportions in distilled dionised water at ambient temperature, 10°C and 30°C. The substance is also miscible in all proportions at pH 5 and pH 9 buffer solutions at ambient temperature. 

Key value for chemical safety assessment

Additional information

Two studies are available on the water solubility. Both studies are reliable and were conducted under GLP according to current guidelines. The two studies showed that the substance is freely soluble in water. The key study is considered to be the one conducted on the test substance of 98.55% purity and the one which additionally examined the effects of temperature and pH on the water solubility.

The water solubility of the test substance could not be assessed using the column elution or flask methods due to its high water solubility/miscibility. Therefore a visual assessment of the water solubility of the test was carried out. Temperature and pH were not found to affect the solubility of the substance.
