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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- EG-Guideline 92/69/EEC A.1.
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Melting / freezing pt.:
- 135.5 °C
- Remarks on result:
- other: refer to "Remarks"
- Remarks:
- no atm. pressure mentioned in the report, but 1013 hPa as standard conditions can be assumed
- Conclusions:
- The test item has a mean melting point of 135.5 °C.
- Executive summary:
The determination of the melting point was carried out by differential scanning calorimetry (DSC) according to EG-Guideline 92/69/EEC A.1. The test substance shows a melting point in the temperature range 110-150 °C with an onset of 135.5 °C.
Reference
The preliminary measurement in a closed glass pan shows an endothermic effect (melting) in the range 110 -155 °C, with an onset of 136.6 °C.
In aluminium pans, the diagrams show the endothermal effect (melting) in the range between 110 and 150 °C, with a medium onset of 135.5 °C and a second endothermal effect (boiling) is in the range between 265 and 345 °C, directly followed by an exothermal effect beginning at about 345 °C.
Description of key information
The determination of the melting point was carried out by differential scanning calorimetry (DSC) according to EG-Guideline 92/69/EEC A.1. The test substance shows a melting point in the temperature range 110-150 °C with an onset of 135.5 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 135.5 °C
Additional information
No atm. pressure is mentioned in the report, but 1013 hPa as standard conditions can be assumed. This does not affect the chemical safety assessment.
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).
