Results and discussion
Water solubility
- Water solubility:
- > 9.28 - < 17.2 g/L
- Temp.:
- 20 °C
- pH:
- > 5.69 - < 5.8
- Details on results:
- The water solubility of Yellow LF 6881 was determined to be 13.24 3.96 g/L (95% confidence interval) at 20 °C ± 0.5 °C using the flask method for the performance of the main test.
Any other information on results incl. tables
The calibration solutions were prepared on each analytical occasion.Thecalibration sampleswere analysed by HPLC with three parallel injections from each.
The test item concentrations were calculated with the help of the calibration equations given in Table 1.
One exemplary calibration curve is given in Figure 1.
Representative chromatograms can be seen in the Appendix 3.
