Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Principles of method if other than guideline:
- The water solubility of the test item have been evaluated by a gas-chromatographic method.
- GLP compliance:
- not specified
- Type of method:
- other: gas chromatographic method
- Specific details on test material used for the study:
- - batch No.of test material: 90231/46
- purity: 99.96% - Key result
- Water solubility:
- 0.023 other: weight-weight %
- Incubation duration:
- 1 h
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not indicated
- Key result
- Water solubility:
- 0.023 other: weight-weight %
- Incubation duration:
- 2 h
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not indicated
- Conclusions:
- The water solubility of the test item at 20°C is 230.5 mg/l
- Executive summary:
Due to the test item nature (gas), the water solubility have been determined according to a specific method. The methods described in the recognised international guidelines are not adapted for gases.
A gas stream of test item has been bubbled into a flask containing distilled water. Then samples are taken and analysed by gas chromatography.
The water solubility is express as the mean of the data obtained after 1 and 2 h of incubation at 20°C.
The water solubility of the test item is 230.5 mg/l.
Reference
The water saturation already occurs after one hour: the value after two hours is within the experimental error. The average value of 230.5 mg/l represents the water solubilty of the test item, according to the experimental method used.
The final analysis after degassing the solution, shows that the test item is no more present.
The limit value of the analysis method is < 5ppm (weight-weight concentration).
Description of key information
Due to the test item nature (gas), the water solubility have been determined according to a specific method. Indeed, the methods described in the recognised international guidelines are not adapted for gas.
A gas stream of test item has been bubbled into a flask containing distilled water.Then samples are taken and analysed by gas chromatography.
The water solubility is express as the mean of the data obtained after 1 and 2 h of incubation at 20°C.
Key value for chemical safety assessment
- Water solubility:
- 230.5 mg/L
- at the temperature of:
- 20 °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.
