Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Melting / freezing point: -59 °C.  

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-59 °C

Additional information

A melting/freezing point of -59 °C is reported by HSDB (2010) and BASF AG (1985) for the substance 2 -dimethylaminoethanol. The peer - reviewed database GESTIS states that the substance will decompose when heated.
