Crystallization and melting of MTDID 49220 were not observed by experiments on the DSC (range = approximately -90 °C to 400 °C). Two subsamples of MTDID 49220 were then placed in freezers for 66 hours at -19.3 ± 0.5 °C and at -83.4 °C ± 1.8 °C, respectively. After storage, it was visually observed that the test substance was a liquid. Based on this it was concluded that the melting temperature of the test substance is < -80 °C.
Applicant's summary and conclusion
- Conclusions:
- A melting point of < -80 °C was observed for MTDID 49220 as determined by EU Method A.1.
- Executive summary:
The melting point of MTDID 49220 was tested using differential scanning calorimetry (DSC). Crystallization and melting of the test substance was not observed by DSC. Two subsamples of MTDID 49220 were then placed in freezers for 66 hours at -19.3 ± 0.5 °C and at -83.4 °C ± 1.8 °C, respectively. After storage it was visually observed that the test substance was a liquid. Based on this it was concluded that the melting temperature of the test substance is < -80 °C. The study was conducted in accordance with EU Method A.1 and was GLP compliant; therefore the study is considered reliable without restrictions.
