Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Parameters:
If the concentrations measured in at least the 2 last vessels do not
differ by more than 15%, the test is satisfactory. If the results from
vessels 1, 2 and 3 show a tendency of increasing values, the whole test
should be repeated using longer equilibration times.
Results
The measured amounts of test substance (c = 8.0 g/L) in water after 24,
48 and 72 h are shown below.
24 h |
48 h |
72 h |
1287.45 mg/L |
1349.90 mg/L |
1328.50 mg/L |
The average water solubility is: 1322 mg/L.
In a second experiment 984 mg of test item were solved in 1 L water. The whole amount of test item dissolved and clear aqueous solutions (pH = 3.57) were obtained.
The recovery rate of 101% determined by HPLC/MS lies within the accepted range of 98 to 102 % and is in agreement with DIN EN 15527:2008 -9.
Description of key information
1322 mg/L at 25 °C and pH 3.57 (OECD 105, flask method)
Key value for chemical safety assessment
- Water solubility:
- 1 322 mg/L
- at the temperature of:
- 25 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
