Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- 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
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Melting / freezing pt.:
- -22.9 °C
- Atm. press.:
- ca. 101.3 kPa
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: result relates to glass transition temperature of the substance
- Conclusions:
- No endothermic peak corresponding to melting of the test substance was recorded in the tested temperature range from -50°C to 25°C. On both heating and cooling curves, a glass transition temperature of -22.9°C was determined.
Reference
In both experiment a glass transition was observed between -37 and -16°C on the heating curve. The extrapolated glass transition temperatures were -22.76 and -22.98°C in the initial and follow up experiments respectively. In both experiments, the sample had lost no mass and the consistency and colour of the sample had not changed.
Description of key information
No endothermic peak corresponding to melting of the test substance was recorded in the tested temperature range from -50°C to 25°C. On both heating and cooling curves, a glass transition temperature of -22.9°C was determined which is selected as the key value for chemical safety assessment.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -22.9 °C
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.
