Preliminary Estimation of Water Solubility:
The preliminary water solubility estimation indicated that the solubility of WRS-2390 in Milli RO water was between 100 000 mg.l-1 (100 g.l-1) and 200 000 mg.l-1 (200 g.l-1).
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
WRS-2390 was determined to have a solubility of 281383 mg.lˆ-1 (281.383 g.lˆ-1). The pH of samples was determined to be 4.13 ± 0.07. The study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability & repeatability). - Executive summary:
WRS-2390 was determined to have a solubility of 281383 mg.l-1 (281.383 g.l-1) in Milli RO water.
The solubility of WRS-2390 was determined with reference to OJEC Test A.6, December 1992.
