Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- not specified
- GLP compliance:
- not specified
- Type of method:
- flask method
- Water solubility:
- 660 g/L
- Temp.:
- 20 °C
- pH:
- 0.8
- Details on results:
- In some cases the PGM concentrations measured by ICP-OES showed a tendency of increasing values at each equilibration time. If the last two vessels varied by less than 15%, the test was deemed satisfactory.
- Conclusions:
- The water solubility of ruthenium acetate is 660 g/L of solution at 20.0 ± 0.5°C.
- Executive summary:
Gregory (2014) followed a standard method and the results are reported in a published paper. The water solubility of ruthenium acetate is 660 g/L of solution at 20.0 ± 0.5°C.

Description of key information
The water solubility of ruthenium acetate is 660 g/L of solution at 20.0 ± 0.5 °C.
A24h TDp screening test showed a Ru release of 81-82% at pH 6 and 8 (Brouwers, 2020).
Key value for chemical safety assessment
- Water solubility:
- 660 g/L
- at the temperature of:
- 20 °C
Additional information
Gregory (2014) followed a standard shake flask method and is reported in a published article. It is suitable for use as the key study for this endpoint. The water solubility of ruthenium acetate is 660 g/L of solution at 20.0 ± 0.5 °C.
Hogg and Bartlett (1996) is included as a supporting study. It is GLP compliant and based on a guideline and is considered suitable for use as the key study for this endpoint. The authors state that the standard A.6 Method is not applicable due to very high saturation mass concentration. An alternative testing scheme was devised which yielded a lower limit value for water solubility. Samples prepared at greater than approximately 660 g/L would have produced unfilterable, inseparable mixtures. The water solubility of ruthenium acetate is > 660 g/L of solution at 20.0 ± 0.5°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
