melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Reliable information from standard operating procedure; measurement according to company guideline
Principles of method if other than guideline:
Determination of melting point; measurement according to company guideline.
Type of method:
thermal analysis
Key result
Melting / freezing pt.:
174 °C
Decomp. temp.:
> 450 °C
Remarks on result:
other: Sharp endothermic peak at melting point

A minor exorthermic process was observed in the 254 - 300°C region. This may lead to a pressure increase in closed systems, if it is due to a partial decomposition of the reaction mass.

The decomposition test shows a small endothermic peak at 357 - 410°C. This most likely corresponds to a non-exothermic composition.

Description of key information

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
174 °C

Additional information

no decomposition up to 450°C
