Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-12 °C

Additional information

Several reliable literature sources report the melting point of trimethylenediamine to be between 11.8°C and 12°C. The value which originates from Beilstein which is a peer reviewed data base is 12°C. Thus the melting point of 12°C at ambient pressure is regarded to be reliable for trimethylenediamine.
