- Adequacy of study:
- key study
- Study period:
- 10 Jan 2017 to 27 Feb 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Version / remarks:
- July 1995
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- May 2008
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7840 (Water Solubility)
- Version / remarks:
- March 1998
- GLP compliance:
- yes
- Type of method:
- flask method
- Key result
- Water solubility:
- 1.2 mg/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- 6.2
- Details on results:
- The final average solubility result, based on the two flow rates is 1.2 mg/L. The final total relative standard deviation, based on the two flow rates is 4.4 %. The results are tabulated in 'Any other information on results incl. tables'
- Conclusions:
- The water solubility of the test substance was determined to be 1.2 mg/L in water at 20 °C and pH 6.2.
- Executive summary:
The water solubility of the test substance has been determined using the flask method in accordance with OECD TG 105, the EU method A. 6. and the EPA test guideline OPPTS 830.7840 and in compliance with GLP. The solubility, correct to two significant figures, of the pure test substance in water was determined to be 1.2 mg/L at 20 °C and pH 6.2.
