Results and discussion

Melting / freezing point
Remarks on result:
other: Melting of the test substance was not observed < 400°C (673K)

Any other information on results incl. tables

PRELIMINARY TEST WITH TGA

No significant weight loss was observed. At 550°C the sample weight had decreased by 0.37%. After the experiment the sample appeared to have been unchanged, i.e. no decomposition and/or evaporation were observed.

DSC EXPERIMENT

No effects were observed < 400°C which were due to melting and boiling of the test substance. After the experiment the sample appeared to have been unchanged, i.e. no decomposition and/or evaporation were observed.

Applicant's summary and conclusion

Conclusions:
In a GLP-compliant study in accordance with EC A.1, OECD 102 and EPA OPPTS 830.7200 using differential scanning calorimetry, no melting up to 400°C was observed for the substance. It was therefore concluded that the substance has no melting temperature.
