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:
yes (incl. QA statement)

Key result
Decomposition:
yes
Decomp. temp.:
>= 184 °C
Remarks on result:
other: Test item decomposed without melting
Remarks:
the samples were observed to darken at temperatures above approximately 184 °C, indicating decomposition.
Conclusions:
The melting temperature of the test item was not determinable as the test item decomposed at temperatures above approximately 184 °C without melting.
Executive summary:

The melting temperature of the test item was investigated in a study performed according to OECD 102 and EC Method A.1. guidelines. The melting temperature of the test item was not determinable as the test item decomposed at temperatures above approximately 184 °C without melting.

The study is a GLP compliant, guideline experimental study, and is acceptable without restrictions.
