Group 1 mean equivalent concentration: 3.81 x 10-2 g/l
at 20.0 ± 0.5ºC
Group 1 range:
3.58 x 10-2 to 4.27
x 10-2 g/l
Group 2 mean equivalent concentration: 1.16 x 10-2 g/l
at 20.0 ± 0.5ºC
Group 2 range: 1.07 x 10-2 to 1.30
x 10-2 g/l
Validation:
The linearity of the detector response with respect to concentration was assessed over the nominal concentration range of 0 to 50 mg/l. This was satisfactory with a correlation coefficient of greater then or equal to 0.997 being obtained for the two groups monitored.
Discussion:
In the absence of definitive purity values for the test material, all calculated concentration values have been reported as equivalent test material concentrations. That is, the concentration calculated for any individual group/component is equivalent to that specified concentration of test material having been successfully dissolved. The test material has been quantified separately for the two distinct groups of peaks eluting at approximately 5 minutes and 10 minutes respectively.
It is evident from the information obtained in the hydrolysis study (see Section 10) and data relating to the pH of the test material in water that negligible hydrolysis of the sample solution occurred during the course of the water solubility test.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of the test material has been determined to be equivalent to 3.81 x 10-2 g/l of test material in solution at 20.0 ± 0.5°C, monitoring components in the first eluting group, and equivalent to 1.16 x 10-2 g/l of test material in solution at 20.0 ± 0.5°C, monitoring components in the second eluting group. - Executive summary:
Water Solubility: Equivalent to 3.81 x 10-2 g/l of test material in solution at 20.0 ± 0.5°C, monitoring components in the first eluting group, and equivalent to 1.16 x 10-2g/l of test material in solution at 20.0 ± 0.5°C, monitoring components in the second eluting group, using the flask method, Method A6 of Commission Directive 92/69/EEC.
