Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
12/2007 to 03/2008
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
The study was conducted according to an internationally recognised method. The substance is adequately defined (with certificate of analysis). However, some experimental data are missing. Therefore validation applies with restrictions.
Reason / purpose for cross-reference:
reference to same study
according to guideline
OECD Guideline 103 (Boiling point/boiling range)
GLP compliance:
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Sample storage: under nitrogen atmosphere and protected from light
Key result
Boiling pt.:
285.6 °C
Remarks on result:
other: accuracy: +/-0.5 °C

No data on individual measurements (at least two repetitions required).

Patm not recorded, but assumed to be ambient.

Executive summary:

According to OECD guideline, boiling point of the test material was measured at a temperature of 285.6 °C.

Description of key information

Measured b.p. ca 285°C (atmospheric pressure not specified).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
285 °C

Additional information

A reliable study, conducted according to the OECD guideline, is available. Therefore, it is considered as a key study, and the result is retained for purpose of CSA.

Literature value was not taken into account because of a significant difference (-4.6°C), but this may be due to unspecified purity and atmospheric pressure.
