Results and discussion

Melting / freezing point
Remarks on result:
other: Melting of the test substance was not observed at temperatures of ≤ 403.2°C (≤ 676.4K)

Any other information on results incl. tables

The test sample remained unchanged when heated up to the final temperature (403.2°C), which exceeded the pre-set temperature of 399 °C due to slight overheating.

Applicant's summary and conclusion

Conclusions:
The melting temperature of the substance was determined using a capillary method (a melting temperature device with metal block) in accordance with EU Method A.1 (1992) and according to GLP principles. As melting of the substance was not observed at temperatures of ≤ 403.2°C (≤ 676.4K), the substance has no melting temperature (up to 403.2°C).
