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)
- GLP compliance:
- no
- Type of method:
- flask method
- Key result
- Water solubility:
- 21.88 mg/L
- Conc. based on:
- not specified
- Remarks:
- TOC content
- Temp.:
- 20 °C
- pH:
- 5.58
- Remarks on result:
- other: water solubility determined after 4 days. Amount of dissolved test item determined by TOC analysis. The pH of the test item after 4 days was measured at 30°C.
- Conclusions:
- The water solubility of the item was determined to be 21.88 mg/L at 20°C, and therefore determined to be slightly soluble.
- Executive summary:
The water solubility of the item was determined by using the Flask method of OECD TG 105. The chemical amount dissolved in water was determined by Total Organic Carbon (TOC) content. The water solubility was determined to be 21.88 mg/L at 20°C. The study is reliable with restrictions, being non-GLP, but having followed a standard guideline.

Description of key information
The water solubility of the test item was determined to be 21.88 mg/L at 20°C.
Key value for chemical safety assessment
- Water solubility:
- 21.88 mg/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of the test item was determined by using the Flask method of OECD TG 105 with the chemical amount dissolved in water determined by Total Organic Carbon (TOC) content. The study is reliable with restrictions, being non-GLP, but having followed a standard guideline (2013).
