Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
June 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:

Type of method:
capillary method
Key result
Decomposition:
yes
Decomp. temp.:
197.6 °C

The following values were recorded:

 Decomposition  Begin  Test End
 First determination  198.1 °C (471.3 K)  223.8 °C (497.0 K)
 Second determination  197.6 °C (470.8 K)  223.3 °C (496.5 K)
Conclusions:
As the test substance decompose before melting and boiling no validity criteria must be considered.

The determination was performed in duplicate. In both determinations, no melting point could be detected, because of decomposition of the test substance. Therefore no boiling point could be determined.
Beginning decomposition was determined with
197.6 °C (470.8 K)
