Description of key information

167 °C at ambient pressure (OECD 102/EU A.1, DSC)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
167 °C

Additional information

Based on the DSC results, the substance was evaluated to show polymorphic behaviour, i.e. it can exist in more than one crystal structure. Upon heating, various transitions to more stable crystal structures were observed; the reported value of 167 °C refers to melting of the most stable crystalline phase.
