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:
0.1 and 50 mg/L of the substance were intensively stirred in DMSO and 1,2 -propyleneglycol at room temperature for 72 hours. After dilution with methanol the UV-spectra were compared with the initial ones. there was no difference.
