Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2000
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Guideline:
- other: DTA Thermoanalysis
- Deviations:
- not specified
- Principles of method if other than guideline:
- DTA measurement
- GLP compliance:
- no
- Type of method:
- differential thermal analysis
- Key result
- Remarks on result:
- not determinable
- Conclusions:
- The substance shows a melting point of 115.2 °C. In the Differential Thermal Analysis (DTA) the substance shows immediately after finishing the melting process an exothermic peak followed by an endothermic peak. This means that the substance changes its composition; a change of the solid state form can be excluded since there was no recrystallization observed in the hot stage microscope up to 170°C. As a conclusion a boiling point cannot be determined.
- Executive summary:
The substance shows a melting point of 115.2 °C. In the Differential Thermal Analysis (DTA) the substance shows immediately after finishing the melting process an exothermic peak followed by an endothermic peak. This means that the substance changes its composition; a change of the solid state form can be excluded since there was no recrystallization observed in the hot stage microscope up to 170°C. As a conclusion a boiling point cannot be determined.
