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:
- 22 May 2018 - 23 May 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:
- 27 July 1995
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Specific details on test material used for the study:
- The test material was pulverised in an agate mortar and then dried for about 24 hours in a desiccator.
- Storage conditions: The test material was stored in a dark storage place at room temperature.
- Test material identification and stability under storage: The infrared (IR) spectrum of the test material measured at the test facility 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 storage conditions. - Key result
- Melting / freezing pt.:
- >= 173.4 - <= 175.6 °C
- Remarks on result:
- other: No information on atm pressure - assumed standard atmospheric pressure
- Remarks:
- Because the difference between the temperature at the beginning and at the final stage of melting exceeded the measurement error (± 0.5 °C), the melting point of the test material was given as the range between the average of two measured values at the beginning of melting and that at the final stage of melting.
- Conclusions:
- Under the conditions of this study, the melting point of the test material is 173.4 °C to 175.6 °C.
- Executive summary:
The melting point of the test material was determined according to the standardised guideline OECD 102 and under GLP conditions, following the capillary method. Because the difference between the temperature at the beginning and at the final stage of melting exceeded the measurement error (± 0.5 °C), the melting point of the test material was given as the range between the average of two measured values at the beginning of melting and that at the final stage of melting.
Under the conditions of this study, the melting point of the test material is 173.4 °C to 175.6 °C.

Description of key information
The melting point of the test material is 173.4 °C to 175.6 °C.
Key value for chemical safety assessment
Additional information
The melting point of the test material was determined according to the standardised guideline OECD 102 and under GLP conditions, following the capillary method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Because the difference between the temperature at the beginning and at the final stage of melting exceeded the measurement error (± 0.5 °C), the melting point of the test material was given as the range between the average of two measured values at the beginning of melting and that at the final stage of melting.
Under the conditions of this study, the melting point of the test material is 173.4 °C to 175.6 °C.
