Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Study period:
2010-01-11 to 2010-01-20
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
The study was conducted according to an internationally recognised method, and under GLP. However, the heating device and the heating rate were not conform to the recommendations. The test substance composition is adequately characterised with its purity. Therefore validation applies with restrictions.

Key result
Boiling pt.:
337 °C
Atm. press.:
97.2 kPa

Preliminary test: 610 K (337°C) at 97.2 kPa

Determination 1: 610 K (337°C) at 97.2 kPa

Determination 2: 610 K (337°C) at 97.2 kPa

Precision +/- 2 K

Executive summary:

The boiling point of the test substance was measured under GLP according to OECD 103 / EU A2 guideline, Siwoloboff (capillary) method.

Two determinations were performed; individual results were found to fall within accuracy, therefore the mean value is retained.

The boiling point of the test substance is 337°C under 97.2 kPa.

Description of key information

Boiling point = 337°C (under 97.2 kPa)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
337 °C

Additional information

A reliable study, conducted according to a recognized OECD/EC method and under GLP, is available. Despite restrictions regarding the procedure, it is considered as a key study. The result is retained as key data.
