Description of key information
Based on the available data from study report,the water solubility determination of test chemical was done as per the OECD guideline 105 (Water solubility) by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determined to be 2865 mg/L at 25°C. On the basis of this value, test chemical was considered to be soluble in water.
Key value for chemical safety assessment
- Water solubility:
- 2 865 mg/L
- at the temperature of:
- 25 °C
Additional information
Based on the available data from study report,the water solubility determination of test chemical was done as per the OECD guideline 105 (Water solubility) by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determined to be 2865 mg/L at 25°C.
In a supporting study, water solubility of test chemical was tested in 3 flasks-water solubility in each flask was determined to be 1058 mg/l, 1121 mg/l and 1073 mg/l. The mean water solubility was determined to be 1084 mg/L at 20°C.
Additional study from peer reviewed journal and authoritative database indicates the water solubility of test chemical as 1420 mg/l at 25°C by the shake flask method.
In an another study, water Solubility of test chemical was estimated to be 2150 mg/L at 25°C, indicating that test substance was soluble in water.
Thus, based on the available information, test chemical was considered to besoluble in water.
