Administrative data
Link to relevant study record(s)
- 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:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no

- yes
- Type of method:
- capillary method
- Key result
- Melting / freezing pt.:
- >= 185 - <= 190 °C
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- Under the conditions of this study, the observed bias adjusted average melting point of the test material was 185 to 190 °C. No colour change was observed.
- Executive summary:
The melting point of the test material was investigated in accordance with the standardised guideline OECD 102 under GLP conditions.
The calibration substance, phenanthrene, gave an average melting point of 97 to 99 °C, which, when compared to the expected melting point of 99 to 101 °C, indicated a bias of 2 °C. The results for the test material were elevated 2 °C to account for this bias.
Under the conditions of this study, the observed bias adjusted average melting point of the test material was 185 to 190 °C. No colour change was observed.
Reference
The calibration substance, phenanthrene, gave an average melting point of 97 to 99 °C, which, when compared to the expected MP of 99 to 101 °C, indicated a bias of 2 °C. The MP results for the test material were elevated 2 °C to account for this bias. The observed bias adjusted average MP of the test material was 185 - 190 °C. No colour change was observed.
Description of key information
The melting range was determined to be 185 to 190 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 185 °C
Additional information
The melting range of the test material was determined following the capillary tube method in accordance with OECD 102 under GLP conditions (Vizon SciTec Inc., 2004). The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Under the conditions of this study, the melting range was determined to be 185 to 190 °C; no colour change was observed.
