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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Boiling point
Administrative data
- Endpoint:
- boiling point
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid which decomposes before boiling
Cross-reference
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 07 March 2017 - 09 May 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Version / remarks:
- 1998
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- 250 °C
- Remarks on result:
- other: no melting point
- Conclusions:
- Melting of the test item was not observed below the temperature at which reaction and/or decomposition started (250°C)
- Executive summary:
Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200.
Melting and/or boiling of the test item was not observed below the temperature at which reaction and/or decomposition started (250°C)
TGA EXPERIMENT (PRELIMINARY TEST)
Significant decrease of weight from 300°C. 25% weight loss at 445°C and 44% weight loss at 549°C.
After the experiment, a grey/brown residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item.
DSC EXPERIMENT
An endothermic peak between 250°C and 400°C was observed. After the experiment, a grey residue remained in the sample container. Based on this, the effect was due to reaction and/or decomposition of the test item.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
