Results and discussion
Water solubility
- Key result
- Remarks on result:
- not determinable
- Remarks:
- due to hydrolysis of the substance
- Details on results:
- During the preliminary tests the test item showed to be not stable in an aqueous solution and therefore no water solubility could be determined.
Applicant's summary and conclusion
- Conclusions:
- The water solubility of 1,8-Dichloranthrachinon could not be determined due hydrolysis of the substance.
- Executive summary:
The water solubility of the test item 1,8-Dichloranthrachinon in demineralized water could not be determined in a GLP study (2018). According to OECD 105 and OPPTS 830.7840 the test item has to be stable in water. During the preliminary tests the test item showed to be not stable in an aqueous solution and therefore no water solubility was determined.
A test solution of the test item was measured after approx. three and 24 hours of stirring in demineralized water. After approx. three hours eight new signals (components) were found, of which four were already measured within the material balance, but in another ratio.
After 24 hours only one signal of one of the decomposition products could be measured and all other signals disappeared. The concentration of the test item measured at this time is determined to be 0.077 mg/L.
Result: The water solubility could not be determined.
