Reference
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:
other: GLP compliant guideline study, available as unpublished report, no restrictions, fully adequate for assessment.
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
yes (incl. QA statement)
Type of method:
thermal analysis
Remarks:
differential scanning calorimeter
Key result
Melting / freezing pt.:
< -90 °C
Atm. press.:
102.2 kPa
Decomposition:
no
Sublimation:
no
Remarks on result:
other: The substance did not show melting above -90ºC
Conclusions:
The test substance did not show melting above -90 °C at an atmospheric pressure of 102.2 ± 0.1 kPa.
Executive summary:

Using a differential scanning calorimeter, the sample was cooled from 25 °C to -90 °C at a rate of 5 °C / minute. No effects were observed. The melting temperature was concluded to be < -90 °C at an atmospheric pressure of 102.2 ± 0.1 kPa.
