Description of key information

Key value taken from published data. 

Key value for chemical safety assessment

Relative density at 20C:

1.329

Additional information

Three references are available for inspection. The reference values closely matches the registrants experience of the substance and is considered suitable for use, on the basis of a weight of evidence approach. The lower value is chosen as the key study, as this is presented at the specified temperature of 20 deg C. As the substance is a gas, this relative density calculation is presumed to be calculated with respect to dry air at a temperature of 20 °C and a pressure of 101.325 kPa absolute.
