Key value for chemical safety assessment

Flash point at 101 325 Pa:
92 °C

Additional information

Several reliable authoritative secondary sources reported the flash point of 1-Methylimidazole as result from experimental studies to be 92°C to 92,1°C at 1013 hPa. The value from GESTIS was chosen as key parameter for the flash point. A flash point of 92°C at 1013 hPa is regarded to be reliable for 1-vinylimidazole.

The following classification criteria are met:

Category 4 (flammable liquids and vapour) of UN GHS: flash point >= 60 °C and <= 93 °C
