Results and discussion

Test substance stable:
yes

Any other information on results incl. tables

The test substance is stable and homogeneous for more than 72 hours in DMSO (0.1 and 50 mg/mL) and in 1,2-propylene glycol (0.1 and 50 mg/mL) at room temperature.

Intensive stirring is necessary for a homogeneous dispersion. About 4 hours is necessary to get a homogeneous dispersion.

Applicant's summary and conclusion

Conclusions:
The test substance is stable and homogeneous for more than 72 hours in DMSO (0.1 and 50 mg/mL) and in 1,2-propylene glycol (0.1 and 50 mg/mL) at room temperature.
Executive summary:

The stability of the test substance in organic solvents was determined by UV-vis spectrometry.

The test substance is stable and homogeneous for more than 72 hours in DMSO (0.1 and 50 mg/mL) and in 1,2-propylene glycol (0.1 and 50 mg/mL) at room temperature.
