Description of key information

Boiling Point (tetramethyl orthosilicate): 121-122°C

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
121 °C

Additional information

A boiling point range of 121-122°C was reported in a handbook which has been subject to peer review and in which the original sources are traceable. This result is considered to be reliable and selected as key study. A boiling point of 122°C was also reported for the substance in a company secondary data source using a relevant test method, although full details are not available, the result is considered reliable. A predicted value of 123°C was determined for the substance using a validated QSAR method. In other supporting sources to which no reliability could be assigned, boiling point values ranging from 121 - 122°C were reported for the substance. The supporting studies are in good agreement with the key data.
