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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guidelines for Testing of Chemicals, Section 1 – Physical-Chemical Properties No: 113 “Screening Test for Thermal Stability and Stability in Air ”
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Other quality assurance:
- other: Not specified
- Type of method:
- other: Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC)
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 310 °C
- Remarks on result:
- not determinable
- Remarks:
- Between -80 °C to 450 °C no melting detected
- From –60 to -40 °C an endothermic effect is visible which could indicate a glass transition
- In the range of approx. 310 and approx. 430 °C an endothermic effect could be detected which could indicate decomposition of the test item
- The decomposition of the test item is indicated by the brownish-blackish residue in the crucible after finalization of the test
- Since no endothermic phases indicating melting could be detected, no further investigations were carried out
- Conclusions:
- Between -80 °C to 450 °C no melting could be detected. From -60 to -40 °C an endothermic effect is visible which could indicate a glass transition (Opala, 2018).
- Executive summary:
The thermal stability and decomposition point by Differential Thermal Analysis (DTA)/Differential Scanning Calorimetry (DSC) was determined according OECD 102/OECD 113. Between -80 °C to 450 °C no melting could be detected. From -60 to -40 °C an endothermic effect is visible which could indicate a glass transition. In the range of approx. 310 and approx. 430 °C an endothermic effect could be detected which could indicate decomposition of the substance.

Description of key information
Between -80 °C to 450 °C no melting could be detected. From -60 to -40 °C an endothermic effect is visible which could indicate a glass transition (Opala, 2018).
Key value for chemical safety assessment
Additional information
In the range of approx. 310 °C and approx. 430 °C an endothermic effect could be detected which could indicate decomposition of the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
