Reference
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).

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.

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.

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.
