Description of key information

Key study: Test method according to OECD 102 and EU method A.1. GLP study. Decomposition of the test substance was indicated by a significant change of colour at about 155 °C.

Supporting study: A calculation method was used to determine the melting point since decomposition was observed in the experimental part of the study. The estimated melting point is 212.6ºC.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
212.6 °C

Additional information

Decomposition indicated by a significant change of colour at 155 ºC.
