Results and discussion

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:

After 72 hours stirring in DMSO (0.1 and 50 mg/ml) at room tempera­ture and 72 hours stirring in 1,2-propylene glycol (0.1 and 50 mg/ml) at room temperature the batches were diluted with methanol and a UV-vis spectrum was prepared and compared with the initial ones.There was no difference
