Description of key information

Using the molecular weight of the substance (113.99 g/mol), the density at 20 °C in air (101.3 kPa) was estimated by calculation to be 4.74 g/L using the Ideal Gas Law.

Key value for chemical safety assessment

Relative density at 20C:
4.74

Additional information

In accordance with Column 2 adaptation statement of REACH (Regulation 1907/2006/EC) Annex VII, an experimental study for the determination of the (relative) density does not need to be conducted as the substance is a gas under normal circumstances. In such a case, an estimation based on calculation shall be made from its molecular weight and the Ideal Gas Laws:

Using the molecular weight of the substance (113.99 g/mol), the density at 20 °C in air (101.3 kPa) was estimated by calculation to be 4.74 g/L using the Ideal Gas Law.
