Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14.09.2018 - 20.09 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Specific details on test material used for the study:
- 200 μL of HPLC grade water was added to 502 mg of test material in a 2 mL clear glass vial.
- Key result
- Water solubility:
- > 1 000 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- Remarks on result:
- other: pH value
- Remarks:
- The pH is ordinarily only required to be reported for solutions used during formal analysis. Since in this case only preliminary informal testing was undertaken, the pH has not been included in the final report.
- Details on results:
- After shaking the mixture for a few minutes, a green solid remained in the lower half of the sample with a clear dark green solution in the upper portion of the sample. An additional 275 μL of HPLC grade water was added to the sample. The sample was sonicated for 30 minutes in an ultra-sonic bath to give a clear dark green solution. The solution was allowed to stand for a further three hours at 20°C. The sample remained as a clear dark green solution, no precipitation / crystallisation was observed.
Note: The test material had previously been isolated from an aqueous solution and dried to a water content of 2.25 %. - Conclusions:
- Estimated Water Solubility: >1000 g/L

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.
