Description of key information
> 400 °C (solid state)
340 °C (aqueous solution)
Key value for chemical safety assessment
Additional information
No self-heating was observed for the substance in a solid state.
The auto-ignition temperature of the aqueous solution of the substance (353 g/kg solution in water) was determined according to EU Method A.15.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
