Reference
Sample stirring | Concentration obtained on the basis of standard curve | Absorbance | Dilution factor | Solubility value obtained (mg/L) |
24 hour | - | - | - | - |
48 hour | 7.4837 | 0.3377 | 40000 | 299348 mg/L |
72 hour | 7.5623 | 0.3413 | 40000 | 302492 mg/L |
Considering the water solubility for 48 hrs and 72 hrs the mean water solubility was calculated as follows:
Mean water solubility value for 48 hour run sample + 72 hour run sample
=(299348 + 302492)/2
=300.920 g/L
Description of key information
The water solubility determination of test chemical was done as per the OECD guideline 105 and by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determined to be 300.920 g/L at 25°C.
Key value for chemical safety assessment
- Water solubility:
- 300.92 g/L
