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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 701-407-2 | CAS number: -
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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: differential scanning calorimetry (DSC)
- Remarks on result:
- other: The sample does not display a freezing point on cooling
- Conclusions:
- The sample does not display a freezing point on cooling. It does have a glass transition with an average
onset of 285.1 K (11.9°C). The sample also has a small broad melt in the 343 to 386 K (74 to 113°C)
range. The melt does not reproduce well in the replicates. It is thought that this may be a small amount
of crystalline material forming in the otherwise amorphous liquid. - Executive summary:
The sample does not display a freezing point on cooling. It does have a glass transition with an average
onset of 285.1 K (11.9°C). The sample also has a small broad melt in the 343 to 386 K (74 to 113°C)
range. The melt does not reproduce well in the replicates. It is thought that this may be a small amount

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
