Description of key information

Melting point (1,1,1,3,3,3-hexamethyldisilazane): -76.2°C at 1013 hPa (EU Method A.1)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-76.2 °C

Additional information

A measured melting point of -76.2°C ± 1.9°C was determined for the substance in accordance with a relevant test method and in compliance with GLP. The result is considered to be reliable and selected as key study. In available secondary sources to which reliability could not be assigned, melting point values of -70°C, -80°C and <-78°C were reported for the substance.
