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:
- November 2016
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Specific details on test material used for the study:
- Batch No ECF8103
- Key result
- Water solubility:
- ca. 873.4 mg/L
- Conc. based on:
- test mat.
- Incubation duration:
- 9 d
- Temp.:
- 20 °C
- pH:
- >= 6 - <= 7
- Details on results:
- No dependence of water solubility on the nominal concentration (5-30 g/L) was observed. The standard deviation of the samples which were used for the calculation of water solubility at the plateau was 25.8 mg/L, corresponding to a relative standard deviation of 3.0 %.
- Conclusions:
- Result of the main test: Water solubility: 873.4 ± 25.8 mg/L at 20.0 °C (0.8734 ± 0.0258 kg/m3 (SI units))
Reference
Due to the pre-test the solubility was expected to lie above 10 mg/L, therefore the flask method was used according to the guideline.
Description of key information
For the water solubility of 2,2'-Azobis (4-methoxy-2,4-dimethylvaleronitrile) the following value was determined:
873.4 ± 25.8 mg/L at 20.0 °C (according to 0.8734 ± 0.0258 kg/m3 (SI units)
No dependency of solubility on amount of the test item (nominal load) was perceived.
Key value for chemical safety assessment
- Water solubility:
- 873.4 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).
