Executive summary:

Melting point (pure grade substance): 69.4 °C

Description of key information

Melting point (Das, pure grade substance): 69.4 °C

Melting range (Rodler, technical grade substance): 61.4 °C - 69.0 °C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
69.4 °C

Additional information

Two guideline studies are available. Both are considered to be reliable and adequate. The study with pure grade substance is considered more relevant, and is carried forward for use in risk assessment, classification and labelling.
