Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
26 Jan-6 Mar 2012
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
Type of method:
thermal analysis
Melting / freezing pt.:
-43 - 143 °C
Decomp. temp.:
ca. 212 °C


The test item shows probably a melting area of the main component between -43 °C and 143 °C (in the 1. - 2. heating run) according to the definition in the OECD Guideline 102 (mean value from repeat determinations; 1stmelting).

-43 °C-143 °C (from first measurement)

-43 °C-144 °C (from second measurement)

-44 °C-143 °C (from third measurement)

The cooling runs show a crystallisation at 71 °C.

From 212 °C, the test item shows most probably a thermal decomposition and evaporation of the decomposition components.

Description of key information

-43 to 143 °C. 

Key value for chemical safety assessment

Additional information

The melting range of the substance was determined by Differential Scanning Calorimetry according to OECD Guideline 102.

The temperature range represents the melting area of the main component.

The substance decomposes at ca. 212 °C.
