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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- supporting study
- Study period:
- n/a
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Guideline:
- other: no guideline followed
- Version / remarks:
- scientific calculation method
- Principles of method if other than guideline:
- Estimation via Blagden’s law
- GLP compliance:
- no
- Type of method:
- other: calculation
- Key result
- Melting / freezing pt.:
- ca. -12.12 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- The melting point was estimated using a scientific calculation method. The magnitude of the freezing point is reasonable and can be hence considered sufficiently reliable.
- Executive summary:
The freezing point of the solution can be estimated to -12.12°C via Blagden’s law.
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2020-08-07
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Guideline:
- other: Differential scanning calometry
- GLP compliance:
- not specified
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- >= 87.2 °C
- Atm. press.:
- 1 013 hPa
- Remarks on result:
- other: Glass transition = 28.8 °C (Onset)
- Conclusions:
- The substance (solid) was heated under well-documented conditions, so the results can be considered reliable.
- Executive summary:
THe melting point of the substance was determined via DSC. Glass transition = 28.8 °C (Onset), Melting point = 87.2 °C (Onset)

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.
