Remarks on result:
other: Relative density is dimensionless.
Conclusions:
A density value of 0.90 g/cm³ at 20 °C has been obtained for the test substance using an accepted calculation method. The result is considered reliable.

Description of key information

Diethoxy(dimethyl)silane: 0.9 g/cm³ at 20°C (QSAR)

Key value for chemical safety assessment

Additional information

A predicted density value of 0.9 g/cm³ at 20°C was obtained using an appropriate calculation method. The result is considered to be reliable. This is supported by a measured value of 0.84 g/cm³ at 20°C from a secondary source (company data).
