- 211.7 °C
- Atm. press.:
- 95.2 kPa
- Decomposition:
- no
- Remarks on result:
- other: Mean based on two assays
- Conclusions:

- Executive summary:
A study was conducted to asses the boiling point of the test material in accordance to OECD 102 and EU method A.1 under GLP conditions.
Two experiments were conducted through Differential Scanning Calorimetry. An aliquot of test material was placed into a crucible. The lid was fitted and the crucible was placed in the DSC analyzer. The melting point was calculated automatically by the Setsoft program by integration of the curves obtained: "Heat flow as a function of the temperature". The test was valid as the results obtained for the standard used conformed to the expected value. Under the conditions of the study, the melting point of the test material was 211.7 °C.
Reference
Melting point of the test item in assay 1: 211.9 °C
Melting point of the test item in assay 2: 211.5 °C
Description of key information
Under the conditions of the study, the melting point of the test material was 211.7 °C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 211.7 °C
Additional information
A study was conducted to asses the melting point of the test material in accordance to OECD 102 and EU method A.1 under GLP conditions. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
Two experiments were conducted through Differential Scanning Calorimetry. An aliquot of test material was placed into a crucible. The lid was fitted and the crucible was placed in the DSC analyzer. The melting point was calculated automatically by the Setsoft program by integration of the curves obtained: "Heat flow as a function of the temperature". The test was valid as the results obtained for the standard used conformed to the expected value. Under the conditions of the study, the mean corrected melting point of the test material was 211.7 °C.
