Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
yes
Type of method:
thermal analysis
Key result
Decomposition:
yes
Decomp. temp.:
95 °C
Remarks on result:
other: glass transition at -85.3°C, no pressure reported
Conclusions:
There is no melting point up to the decomposition of the substance. No pressure was reported.
Executive summary:

A differential thermal analysis (DTA)-system was used to determine the melting point which conforms with the procedure 'Test method A.1', described in the EC-Guideline. There is no melting point up to the decomposition of the substance. No pressure was reported. A glass transition was observed at -85.3°C and exothermal decomposition started at 95 °C.
