Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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:
269 °C
