Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Comparable to guideline study (EU A.1) with acceptable restrictions.
Principles of method if other than guideline:
Differential scanning calorimetry
Type of method:
thermal analysis
Melting / freezing pt.:
301 °C
Decomp. temp.:
304 °C

The product begins to melt at 301 °C, exothermic decomposition starts at 304 °C. Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (1100 J/g, mean of 2 measurements) is less than the true decomposition energy.

The product begins to melt at 301 °C.
Executive summary:

The thermal behaviour of the test substance was investigated by Differential Scanning Calorimetry (DSC). The test item melts under decomposition starting from 301 °C.

Description of key information

Key study: Differential scanning calorimetry. The test item melts under decomposition starting from 301 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
301 °C
