Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
22 March 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
1995
Deviations:
no
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
- The infrared (IR) spectrum of the test material measured at this laboratory was confirmed to be identical to that provided by the sponsor.
- In addition, the IR spectrum of the test material after the completion of the experiment was the same as that before the start of the experiment, and it indicated that the test material was stable under the storage conditions.
Key result
Decomposition:
no
Remarks on result:
other: No freezing point of the test material observed between -100 and 25 °C.

- The peak corresponding to the melting/freezing point of the test material was not observed on the DSC chart.

- The appearance of the test material sample was the same before and after the measurement (colourless and transparent liquid). The change of test material was not observed.

- Therefore, it is concluded that there is no melting/freezing point of the test material between -100 °C and 25 °C.

Conclusions:
Under the conditions of this study no melting/freezing point of the test material was observed between 25 and -100 °C.
Executive summary:

The melting/freezing point of the test material was investigated in accordance with the standardised guideline OECD 102, under GLP conditions using differential scanning calorimetry.

The test material was exposed to a temperature range of -100 to 25°C at 10°C per minute.

The peak corresponding to the melting/freezing point of the test material was not observed on the DSC chart. The appearance of the test material sample was the same before and after the measurement (colourless and transparent liquid). The change of test material was not observed.

Under the conditions of this study no melting/freezing point of the test material was observed between 25 and -100°C.

Description of key information

Under the conditions of the study no melting/freezing point of the test material was observed between 25 and 100°C.

Key value for chemical safety assessment
