Key value for chemical safety assessment

Relative density at 20C:
0.875

Additional information

The relative density of the test substance is reported to be 0.875 at 20°C. This data was taken from a peer reviewed handbook which is considered reliable for assessment. This is supported by a similar density value of 0.89 g/cm³ at 25°C reported in a secondary source and a predicted density value of 0.93 g/cm³ at 25°C
