melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
14.February 20212
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Guideline study with acceptable restrictions. Valid method according to company guideline /standard operating procedure
Principles of method if other than guideline:
Differential thermal analysis (DTA)
Type of method:
other: Differential scanning colorimetry (DSC)
Key result
Melting / freezing pt.:
269 °C
Decomp. temp.:
276 °C

An exothermic decomposition starts at 276°C. Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (945 J/g) is less than the true decomposition energy. The product begins to melt at 269°C.

Executive summary:

The DTA recorded a melting point of 269°C and decomposition from the melting substance at onset temperature of 276°C.

Description of key information

Melting point at 269°C. Thermal analysis (Differential scanning colorimetry (DSC)).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
