The AIChE DIPPR Database specifies that the uncertainty associated with the boiling point value for octamethylcyclotetrasiloxane as <1%

Conclusions:
A boiling point value of 175°C was reported in a collection of data which has been subject to peer-review and in which the original data sources are traceable. The result is considered reliable.

Description of key information

Boiling point [octamethylcyclotetrasiloxane]: 175°C

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
175 °C

Additional information

A boiling point of 175°C at 101.3 kPa was reported for the substance in two handbooks or collections of reliable data which have been subject to peer-review and in which the original sources are traceable. The results are considered to be reliable. A boiling point of 175.5°C was reported for the substance in a secondary source to which reliability could not be assigned.
