Additional information

A partition coefficient value of 2.7 was obtained for tetramethylsilane using an appropriate calculation method. A secondary source to which reliability could not be assigned gave a value of 3.2. Therefore, a partition coefficient of 3 is used as the key value. Further testing is not considered appropriate because the substance is highly volatile (boiling point 27°C, vapour pressure 80 kPa at 20°C).
