Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
10-30 Apr 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:
differential scanning calorimetry
Melting / freezing pt.:
>= -59 - <= -11 °C
Remarks on result:
other: The temperature range represents the melting area of crystalline subcomponents.


The test item shows a melting area of crystalline subcomponents between -59 °C and -11 °C (in the 1. - 2. heating run) according to the definition in the OECD Guideline 102 (mean value from repeat determinations; 1stmelting from the subcomponent).

-59 °C - -10 °C (from first measurement)

-58 °C - -11 °C (from second measurement)

-60 °C - -12 °C (from third measurement)

The cooling runs show a crystallisation at -21 °C.

Description of key information

-59 to -11 °C (melting of crystalline subcomponents)

Key value for chemical safety assessment

Additional information

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

The temperature range represents the melting area of crystalline subcomponents. The cooling runs show a crystallization at -21 °C.
