Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 31 October - 07 November 2022
- Reliability:
- 2 (reliable with restrictions)
- Justification for type of information:
- Non-GLP study; suitable for registration and classification.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- not specified
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- No further details in study report
- Key result
- Decomposition:
- yes
- Remarks:
- An exothermic peak that corresponds with degradation was observed from 261.2°C (Onset temperature).
- Remarks on result:
- other: No melting or boiling peak was observed throughout the study. For each determination, a step corresponding with glass transition was observed between ~ -6.5°C (Mean Onset Temperature) and ~ 3.8°C (Mean Endset Temperature).
- Conclusions:
- No melting or boiling peak was observed throughout the study. For each determination, a step corresponding with glass transition was observed between ~ -6.5°C (Mean Onset Temperature) and ~ 3.8°C (Mean Endset Temperature).
An exothermic peak that corresponds with degradation was observed from 261.2°C (Onset temperature). From this temperature, the mass started to decrease until the end of the measurement (81.44% total mass loss). Moreover, the DSC signal got disturbed after the peak due the obstruction of the lid hole. - Executive summary:
The purpose of this study was to determine the melting point/melting range and the boiling point of the test item RED HF2.
No melting or boiling peak was observed throughout the study. For each determination, a step corresponding with glass transition was observed between ~ -6.5°C (Mean Onset Temperature) and ~ 3.8°C (Mean Endset Temperature).
An exothermic peak that corresponds with degradation was observed from 261.2°C (Onset temperature). From this temperature, the mass started to decrease until the end of the measurement (81.44% total mass loss). Moreover, the DSC signal got disturbed after the peak due the obstruction of the lid hole.

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.
