Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method C.7 (Degradation: Abiotic Degradation: Hydrolysis as a Function of pH)
- Version / remarks:
- Due to the physical-chemical properties of the test item it is impossible to investigate its hydrolytic propertiesaccording to the EU Commision Regulation (EC) No. 440/2008C.7. According to literature, in auqeous solution stannic chloride is cleaved by hydrlysis
- Deviations:
- yes
- GLP compliance:
- yes

Results and discussion
- Preliminary study:
- Preliminary study:
Because of the difficult handling and high instability of the test item the performance of the hydrolysis test described in the European Commission Regulation (EC)440/2008 C.7 and in the OECD guideline 111 was modified. Nevertheless the observation made during the performance of the test and the calculations showed that in distilled water 90 -96 % of the test item was hydrolized after a time period of 2.5 h. Therefore the tested substance has to be considered as hydrolytically unstable and according to the guidelines no additional testing is required. - Transformation products:
