Water solubility:
74.6 µg/L
Temp.:
20 °C
pH:
7
Details on results:
At a flow rate of 26.4 ml/hour the solubility was determined to be 74.6 μg/L with a standard deviation of 4.5. At a flow rate of 12.8 ml/hour the solubility was determined to be 74.6 μg/L with a standard deviation of 1.5.

Duration: 9 or 10 days (Two complete runs were conducted).

Statistical Methods: No statistical methods were employed.

Water Solubility (20 oC, pH=7): 74.6 μg/L

Description of key information

74.6 μg/l at 20°C, pH=7
190 μg/l at 20°C, pH>=5.5-<=6.5

Key value for chemical safety assessment

Water solubility:
74.6 µg/L
at the temperature of:
20 °C

Additional information

Value taken from GLP study. Other value is significantly higher (190 micrograms per liter), because the assessment of water solubility in such low ranges is very difficult.
