Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Justification for type of information:
- Experimental test result performed using standard test guidelines
- Qualifier:
- according to guideline
- Guideline:
- other: as mention below
- Principles of method if other than guideline:
- Determine water solubility of chemical 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione
- GLP compliance:
- no
- Type of method:
- other: not specified
- Key result
- Water solubility:
- < 1 mg/L
- Conc. based on:
- test mat.
- Remarks on result:
- other: No other detail available
- Conclusions:
- The water solubility determination of test substance 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione was determine to be less than 1 mg/L. Thus chemical 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is considered to be slightly soluble in water.
- Executive summary:
The water solubility determination of test substance 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione was determine to be less than 1 mg/L. Thus chemical 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is considered to be slightly soluble in water.
The solution (100 mg/L test item was weighed out) was prepared with dilution water in brown glass flask one day day prior to application.The stock solution was shaken with 20 rpm for 24 h (rotating shaker 3040, GFL). Undissolved particles were removed by centrifugation (20 min at 3000).
