Materials and methods
Test guideline
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- The purpose of this test is to investigate the hydrolytic behaviour of the test substance as a function of pH. However, in view of the low water solubility (less than 0.02 mg/l, see Huntingdon Life Sciences Report Number CBG 845/032506), the hydrolysis of the test item could not be examined.
- GLP compliance:
- yes (incl. QA statement)
Test material

Constituent 1
Results and discussion
- Preliminary study:
- Technically not feasible due to low water solubility.
- Transformation products:
- not measured
Dissipation DT50 of parent compound
- Key result
- Remarks on result:
- not determinable
- Details on results:
- The hydrolysis of the test item was not examined due to its low water solubility. The water solubility was determined to be less than 0.02 mg/l (see the Huntingdon Life Sciences Report Number CBG 845/032506).
Any other information on results incl. tables
The hydrolysis of the test item was not examined due to its low water solubility. The water solubility was determined to be less than 0.02 mg/l (see the Huntingdon Life Sciences Report Number CBG 845/032506).
Applicant's summary and conclusion
- Conclusions:
- Due to its low water solubility, the test on hydrolysis was technically not feasible. However, due to the structural properties of the test item, hydrolysis is not expected.
