Key result
Water solubility:
0.4 g/L
Conc. based on:
test mat.
Temp.:
20 °C
Remarks on result:
other: pH not specified.
Water solubility:
650 g/L
Conc. based on:
test mat.
Temp.:

Remarks on result:
other: pH not specified.
Conclusions:
The solubility of the test item in water at 20ºC was found to be 0.4 g/L.
Executive summary:

The determination of the water solubility of the test item, using the shake flask method, was carried out by a method similar to OECD 105 (EU A.6, flask method). Successive additions of test item to 100 mL of solvent were performed, and the absorbance of these solutions was measured with a spectrophotometer at 660 nm at different temperatures and times. The final point was considered to be when the absorbance dropped under 0.010 UA. Under test conditions, the solubility of the test item at 20 ºC in water was determined to be 0.4 g/L.

Description of key information

Key value for chemical safety assessment

Water solubility:
0.4 g/L
at the temperature of:
20 °C
