melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
23 May - 3 Aug 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.:
>= -64 - <= 145 °C
Remarks on result:
other: Melting area of crystalline subcomponents


The test item shows a melting area of crystalline subcomponents between -64 °C and 145 °C (in the 1. and 2. heating run) according to the definition in the OECD Guideline 102 (mean value from repeat determinations; 1st melting from the subcomponent).

-65 °C - 146 °C (from first measurement)

-63 °C - 142 °C (from second measurement)

-64 °C - 146 °C (from third measurement)

The 1st cooling run shows a cristallization at 99 °C.

Description of key information

-64 - 145 °C 

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 melting range given corresponds to the melting area of crystalline subcomponents.
