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:
- 22 September 2017 to 27 September 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- - Purity: >98 % This substance has an Unknown or Variable composition, is a Complex reaction product, or a Biological material (UVCB), therefore purity was taken to be 100 %
- Description: Yellow liquid - Key result
- Melting / freezing pt.:
- -60 °C
- Decomposition:
- yes
- Decomp. temp.:
- 100 °C
- Conclusions:
- Under the conditions of the study, no endotherms characteristic of a melting temperature were recorded on either test, therefore the melting temperature is <−60°C, however, an endothermic event characteristic of glass transition was observed, with an onset temperature of −34°C. Various exothermic events were observed from 100 to 400°C, indicating decomposition.
- Executive summary:
In a study performed to the standardized guideline OECD 102, under GLP conditions, the melting point of the test substance was as follows; no endotherms characteristic of a melting temperature were recorded on either test, therefore the melting temperature is <−60°C, however, an endothermic event characteristic of glass transition was observed, with an onset temperature of −34°C. Various exothermic events were observed from 100 to 400°C, indicating decomposition.
Reference
No endotherms characteristic of a melting temperature were recorded on either test, resulting in a melting temperature of <−60°C. However, an endothermic event characteristic of glass transition was seen with an onset temperature of−34°C. Various exothermic events were observed from 100 to 400°C, indicating decomposition

Additional information
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.
