Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- >= 515 - <= 517.2 K
- Remarks on result:
- other: Conducted at atmospheric pressure
Any other information on results incl. tables
Melting was observed to start at 515.7K and the final melting temperature was 517.2K.
Applicant's summary and conclusion
- Conclusions:
- Based on testing using the capillary method at standard atmospheric pressure, the melting point of the substance is 515.7 to 517.2K.
- Executive summary:
The study was conducted by a recognised GLP accredited laboratory, although the study report makes no claim of GLP compliance. Testing was conducted in accordance with method A1 of EEC Directove 84/449/EEC and determined the melting point at atmospheric pressure is in the range 515 to 517.2K.
