Melting / freezing pt.:
> 202 - < 241 °C

Melting was observed between 202 and 241 °C. The onset of this process was at 222.5 °C, with enthalpy of -103.9 J/g.

Conclusions:
Melting range is 202 - 241 °C.
Executive summary:

Method

The test was performed according to internationally accepted testing procedures (OECD 102), using Differential Scanning Calorimetry method for analysis.

Result

Melting was noted in the range of 202 - 241 °C. The onset of this process was at 222.5 °C, with an enthalpy of -103.9 J/g.

Description of key information

Melting point between 202 and 241 °C (onset at 222.5 °C).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
222.5 °C

Additional information

Differential Scanning Calorimetry - OECD 102.

Similar melting point, i.e. 208.28 °C, was predicted by MPBPWIN as implemented in EPI Suite v4.11 tool, using smile notation of the substance as input.
