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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2004-07-08 to 2004-07-09
- 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
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- < -120 °C
- Atm. press.:
- 1 013 hPa
- Remarks on result:
- other: The melting point of test substance does not exsit in the range of measured temperature (-120 to 100°C).
- Conclusions:
- A melting point of <-120°C was determined for the substance in accordance with OECD 102 and in compliance with GLP. The result is considered reliable.
Reference
It is considered that the melting point of test substance does not exist in the range of measured temperature
becasue the peak that was considered endoergic reaction associated melting was not observed in the DSC curve of the test substance.
Description of key information
Melting point [tetrahydrofurfuryl alcohol]: <-120°C (OECD 102)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -120 °C
Additional information
No melting/freezing was observed in the temperature range -120 to 100°C for the substance in a DSC study in accordance with OECD 102 and in compliance with GLP. Therefore, the melting/freezing point of the substance is <-120°C. The result is considered to be reliable and selected as key study. This value is supported by melting point of <-80°C reported in two handbooks or collections of reliable data which have been subject to peer review, and in which the original sources are traceable. Similarly, melting point values of <-94°F (-70°C) and <-80°C were reported in secondary sources to which reliability could not be assigned. The supporting studies are in good agreement with the key study.
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).
