Executive summary:

The freezing temperature of the test substance was determined to be 39.7 °C in a non-GLP test according to OECD 102.

Description of key information

 The freezing temperature of the test substance was determined to be 39.7 °C in a non-GLP test according to OECD 102. 

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
39.7 °C

Additional information

The freezing temperature of the test substance was determined to be 39.7 °C in a non-GLP test according to OECD 102.

This value can be confirmed by an experimental value stated in the database of the EPIWIN program (41.5 °C) and one from the GESTIS database (melting range of 38 - 41 °C).
