Description of key information

Boiling Point [2,4,6-trimethyl-2,4,6-tris(3,3,3-trifluoropropyl)cyclotrisiloxane]: 190°C (QSAR)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
190 °C

Additional information

There is no reliable measured boiling point for the submission substance. A predicted boiling point of 190°C was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable and selected as key study. The prediction does not differentiate between the cis- and trans-isomers. This value is supported by boiling point values of 239°C and 243°C at 1012 hPa and boiling points of 104°C and 95°C at lower pressures of 5.3 hPa and 4 hPa respectively which were reported for the substance (no ratio of isomers reported) in secondary sources to which reliability could not be assigned.
