Melting point / freezing point
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:
- 29 January 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Remarks:
- In-house study
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Differential scanning calorimetry was used. The system has been checked with a certified reference sample, BaCO3, for melting point accuracy and it is within specification.
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 775.7 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- The test item had a melting point of 775.7 +/- 0.7°C.
- Executive summary:
Johnson Matthey (2018) is not GLP-compliant but followed a standard method for determining melting point (differential scanning calorimetry) and is acceptable with restrictions (Klimisch 2). A melting point of 775.7 +/- 0.7°C was determined for the test item.
