Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Density (tetramethyl orthosilicate): 1.03 g/cm3 at 20°C (DIN 51757)

Key value for chemical safety assessment

Additional information

Three reliable data are available for tetramethyl orthosilicate. A density value of 1.03 g/cm3 at 20°C was reported in two of the three available data (Evonik 2007, Lide 1993) which are used in a weight of evidence approach. An estimated density of 0.98 g/cm3 was determined for the substance using a validated prediction method. The predicted value is in good agreement with the other available results.
