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:
- guideline study
- Justification for type of information:
- Experimental test result performed using standard test guidelines
- Qualifier:
- according to guideline
- Guideline:
- other: spectrophotometric analytical method
- Principles of method if other than guideline:
- The water solubility determination of test chemical was done as per the OECD cguideline 105 by spectrophotometric analytical method as per OECD 101.
- GLP compliance:
- no
- Type of method:
- other: spectrophotometric analytical method
- Key result
- Water solubility:
- 56.624 mg/L
- Conc. based on:
- test mat.
- Temp.:
- 29 °C
- Remarks on result:
- other: No other detail available
- Conclusions:
- The water solubility determination of test chemical was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determine to be 56.624 mg/L at 25°C.
Thus the test chemical is considered to be slightly soluble. - Executive summary:
The water solubility determination of test chemical was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determine to be 56.624 mg/L at 25°C.
Thus the test chemical is considered to be slightly soluble.

Description of key information
The solubility of test chemical in water was determine to be 56.624 mg/L at 25°C.
Thus the test chemical is considered to be slightly soluble.
Key value for chemical safety assessment
- Water solubility:
- 56.624 mg/L
- at the temperature of:
- 25 °C
Additional information
The water solubility determination of test chemical was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determine to be 56.624 mg/L at 25°C.
In another study,the solubility of test chemical in water at 25 deg C was determined to be 107.9 mg/l.This value indicates that test chemical is moderately soluble in water.
As the data from experiment has K1 reliability and the test was performed using OECD guidelines which has the value of water solubility as 56.624 mg/l at 25°C, thus considered as key study for the chemical safety assessment.
