Results and discussion
Water solubility
- Water solubility:
- 0.001 mg/L
- Conc. based on:
- test mat.
- Temp.:
- 20.2 °C
- pH:
- >= 6.8 - <= 6.9
- Details on results:
- The water solubility was performed twice because the results of the first measurements 12 and 24 mL/h gave a maximum difference (MD) >30%. It was considered that undissolved system was not yet in equilibrium. Detailed results are archived in the raw data.
The coefficient of variation (CV) (n = 10) was ≤ 30% at both flow rates. It demonstrated that the system was equilibrated at all flow rates.
The maximum difference (MD) on the mean values of the samples at both flow rates was also ≤ 30%. Based on this, the water solubility of the test item is given as the mean value of these measurements.
The turbidity of the eluates was < 0.2 NTU. According to this, no undissolved particles were detected in the eluates.
Small responses were detected in the samples from the blank column. It was considered to derive from carry-over in the analytical system since similar responses were found in the analytical blanks. The maximum contribution to the highest test item sample was 3.7%. It was considered that it has no significant effect on the results of the test samples.
Applicant's summary and conclusion
- Conclusions:
- The column elution method was applied for the determination of the water solubility of V134434.
The water solubility of the test item at 20°C was 0.000799 mg/L.
The pH of the aqueous samples was 6.8 and 6.9.
