EC number: 915-932-1 | CAS number: -
Solubility in organic solvents / fat solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- solubility in organic solvents / fat solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- November 15, 2017 - November 21, 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 116 (Fat Solubility of Solid and Liquid Substances)
- Deviations:
- yes
- Remarks:
- Due to the absence of a valid analytical method, only a visual assessment of solubility could be made.
- GLP compliance:
- yes
- Specific details on test material used for the study:
- Composition: Reaction mass of dipotassium 3,3’-sulphonylbis(benzenesulphonate) and potassium 3-(phenylsulphonyl)benzenesulphonate
Purity: 92.8%
CAS# 63316-33-6 and 63316-43-8
Physical Description:White powder
Stability: Test substance was expected to be stable for the duration of testing.
Expiration Date: December 31, 2018 - Key result
- Medium:
- n-octanol
- Solubility:
- 0.09 g/L
- Temp.:
- 20 °C
- Test substance stable:
- yes
- Conclusions:
- The solubility of the substance in n-Octanol was determined to be 0.09 g/L.
- Executive summary:
In a GLP study according to the Shake Flask method procedures (visual observation only, no analytical determination) as described for water solubility in OPPTS 830.7840, OECD TG 105, and EC Test Method A6, the solubility of the test substance in n-Octanol was determined to be 0.09 g/L and thus considered only slightly soluble in n-Octanol.

Description of key information
In a GLP study according to the Shake Flask method procedures (visual observation only, no analytical determination) as described for water solubility inOPPTS 830.7840, OECD TG 105, and EC Test Method A6, the solubility of the test substance in n-Octanol was determined to be 0.09 g/L and thus considered only slightly soluble in n-Octanol.
Key value for chemical safety assessment
- Solubility in organic solvents at 20°C:
- 0.09 g/L
Additional information
The solubility of the test substance in n-Octanol was determined to be 0.09 g/L.
