Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
14 June 2011
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Comparable to guideline study (EU A.1) with acceptable restrictions
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Principles of method if other than guideline:
DSC measurement according to company guideline.
Type of method:
thermal analysis
Decomposition:
yes
Decomp. temp.:
ca. 282 °C

2 measurements were conducted. No endothermic effects (melting/boiling) were observed.

The test substance starts to decompose at ca. 282 °C with a mean energy of 190 J/g (2 measurements).

Conclusions:
The test item starts to decompose at ca. 282 °C.
Executive summary:

The thermal behaviour of the test substance was investigated by Differential Scanning Calorimetry (DSC). The test substance starts to decompose at ca. 282 °C without prior melting or boiling.
