Reference 3

Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

supporting study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

data from handbook or collection of data

Principles of method if other than guideline:

reliable handbook data, no further details

GLP compliance:

not specified

Boiling pt.:

269 °C

Atm. press.:

1 013 hPa

There is no value given for pressure but assumed to be measured at normal pressure (1013 hPa).

Conclusions:

A boiling point value of 269°C is reported in secondary literature (Handbook).

Description of key information

356.5 °C at 1013 hPa (OECD 103, differential scanning calorimetry)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

356.5 °C

Additional information

The key study is supported by a boiling point of 355 °C determined using a reliable prediction method (QSAR). A measured value of 269 °C was obtained from a reliable peer reviewed handbook.
