Results and discussion
- Test substance stable:
- yes
- Transformation products:
- no
Any other information on results incl. tables
A 0.01% and a 5% slurry of the test substance in DMSO is stable for at least 48 h. The slurry has to be stirred intensively to get a homogeneous distribution of the test substance.
Applicant's summary and conclusion
- Conclusions:
- The test substance is stable in DMSO.
- Executive summary:
The stability of the test substance was determined using UV-vis spectrometry. The test substance was stable in DMSO for more than 48 hours.
