Description of key information

Melting point: -108°C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-108 °C

Additional information

A melting point of 108°C is reported in secondary literature. The reliability of the result could not be assigned. However, this result, supported by melting points reported for the related substances 2,4,6,8-tetramethylcyclotetrasiloxane and decamethylcyclopentasiloxane of -65°C and -38°C

respectively, is sufficient to indicate that the melting point is below -20°C. Therefore, further testing is waived.
