Description of key information

The melting range of NMMO under ambient conditions was determined to be 179-183°C in a GLP study according to test method EC A.1, capillary method (Younis, 2012).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
179 °C

Additional information

For the chemical safety assessment the lower end value of the melting range (179°C) was taken as the key value.
