- 52.9 g/L
- Temp.:
- 20 °C
- pH:
- ca. 4
- Remarks on result:
- other: main component
- Water solubility:
- 13.4 g/L
- Temp.:
- 20 °C
- pH:
- ca. 4
- Remarks on result:
- other: Isomere 2
- Details on results:
- The preliminary test at room temperature showed, that the water solubility of the test itemwas between 30.0 g/L and 67.5 g/L. Therefore, the flask method was performed.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
- Executive summary:
According to OECD Test Guideline 105 the water solubility at 20 °C of the main constituent and isomer 2 of the test item Reactive Golden Yellow HF-RN 1331 was determined to be:
main constituent: Cs = 52.9 g/L (RSD = 0.2 %)
isomer 2: Cs = 13.4 g/L (RSD = 0.4 %)
