Description of key information

Melting point (tetramethyl orthosilicate): 3°C (OECD 102)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
3 °C

Additional information

Two reliable measured values are available for the melting point of tetramethyl orthosilicate. A melting point of 3°C was determined for the substance using a relevant test method. The result is considered reliable and selected as key study. A melting point value of -2°C was reported for the test substance in a collection of reliable data subject to peer review and in which the original sources are traceable. In other available sources to which reliability could not be assigned, melting point values ranging from -4°C to 2°C were reported for the substance. The study recently conducted was selected as key study.
