Description of key information

End point waived as testing scientifically not feasible. Substance would have a very low vapour pressure which is confirmed by EPISuite calculated value (2.15 x 10-14 mmHg) which is less

than minimum permitted value. As such 1 x 10-6 Pa used for CSA purposes only

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The sample did not exhibit a boiling point as the temperature of the event at approximately 310°C was unchanged from atmospheric pressure to 100 mbar (< 1°C). This is clearly a decomposition event and therefore a vapour pressure due to the sample cannot be determined. The end point is thus waived on the basis of testing being scientifically not feasible
