Applicant's summary and conclusion
- Conclusions:
- The solubility of ZK 39 211 in a saturated buffer solution (pH = 7) obtained after equilibration and separation from the insoluble residues were determined using the flask method.Measurements were made at 25 °C in accordance with OECD Testing Guideline No. 105 giving a solubility in aqueous buffer solution at 25 °C with 95 % confidence interval: S = 32.37 +/- 1.35 g/L
- Executive summary:
