Applicant's summary and conclusion
- Conclusions:
- OECD 111 pH dependent aqueous stability was evaluated for the provided test substance. The test substance was incubated for 5 days at 50 C in solutions prepared at a range of pH (pH 4, pH 7 and pH 9). Following the incubation, samples were recovered and dissolved in n-hexane for injection and analysis by liquid chromatogrpahy and refractive index measurement. The retention time of the unincubated test substance was 7.6 minutes as compared to the pH exposed test substance retention time of 7.6 minutes respectively for pH 4, pH7 and pH9. The recovered test substance demonstrated indicated no hydrolytic instability related to pH and testing was concluded.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
