Description of key information

Density dichlorosilane: 4.1 kg/m3 at 25°C (calculated based on the ideal gas laws); 4.129 g/l = 4.129 kg/m3 (Handbook data)

Key value for chemical safety assessment

Additional information

In accordance with Column 2 of REACH Annex VII, the density study does not need to be conducted as the substance is a gas.

The density of dichlorosilane is 4.1 kg/m3 at 25°C calculated based on the Ideal Gas Laws. A density of 4.129 4.1 kg/m3 is reported in a handbook that has been subject to peer-review and in which the data sources are traceable (Haynes 2010 CRC Handbook, p 4-87).
