Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Test dates: Apr.19 to Jul.5, 2013
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
The study was conducted according to an internationally recognised method, and under GLP, but experimental details are missing. The substance is adequately identified. Therefore validation applies with restrictions.
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
Principles of method if other than guideline:
Not applicable
GLP compliance:
yes (incl. QA statement)
Remarks:
GIPC; effective Jun.14, 2012, signed on Jan.10, 2013
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Storage conditions of test material: At room temperature protected from direct sunlight.
Key result
Boiling pt.:
ca. 265.9 °C
Atm. press.:
ca. 1 atm

Three successive tests were retained.


Mean onset for boiling occurred at 265.9 ± 0.1 °C. The validity criteria were fulfilled; the standard deviation within the three replicate assessments did not exceed 0.5 °C.


Therefore, the average value is retained as final result.

Executive summary:

The boiling point of the test substance was determined under GLP according to EU A2 guideline, using
Differential Scanning Calorimetry (DSC) method.


 


Three main runs were performed, and the mean final temperature was retained.


 


Under the test conditions, the mean onset for boiling occurred at 265.9 °C ± 0.1 °C.

Description of key information

Boiling point = 265.9°C (atmP not specified) (experimental, EU A2, DSC, GLP).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
265.9 °C

Additional information

A reliable experimental study, conducted according to a recognized EC method and under GLP, is available. Despite restrictions due to unclear test conditions, it is
considered as key study, and the result is retained as key data.
