Study period:
December 16, 2015
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 102 (Melting point / Melting Range)
not specified
Principles of method if other than guideline:
Study conducted according to the internal method SOP-STR 028 DSC solid state
GLP compliance:
Type of method:
differential scanning calorimetry
Melting / freezing pt.:
> 206 - < 236 °C
Atm. press.:
ca. 1 atm
Decomp. temp.:
> 236 °C

Melting of the substance occurs between 206 and 236 °C, with onset at 223.45 °C and enthalpy of -97.70 J/g. Upon melting, the substance decomposes.

The melting point is between 206 and 236 °C.
Executive summary:


The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.


Melting point between 206 and 236 °C, followed by decomposition.

Description of key information

The melting point is between 206 and 236 °C (onset at 223.45 °C and enthalpy -97.70 J/g); the substance decomposes before boiling.

Key value for chemical safety assessment
