*The relative density D20/4 is the ratio between the measured density of the test substance at 20 °C and the density of water at 4 °C (= 0.99997 g/cm3). The relative density has no dimension.

Check measurement: Density of degassed deionized water at 20 °C: 0.99820 g/cm3

Reference value: 0.9982 + 0.0005 (20 °C)

Conclusions:
A density of 0.906 g/cm³ at 20°C and a relative density of 0.906 were determined in a reliable study conducted according to an appropriate test protocol. It was not conducted according to GLP.

Conclusions:
A density value of 0.9 g/cm3 has been determined for the substance using an appropriate estimation method. The result is considered reliable.

Description of key information

Trimethoxy(2,4,4-trimethylpentyl)silane): 0.906 g/cm³ at 20°C

Key value for chemical safety assessment

Relative density at 20C:
0.906

Additional information

A density value of 0.906 g/cm3 was determined by oscillating densimeter according to EU Test Method A.3. This is supported by a predicted density value of 0.9 g/cm3 determined using a validated QSAR method and a measured density value of 0.9 g/cm3 obtained from a secondary source (company data).
