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:
- 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E 537, Standard method for assessing the thermal stability of chemicals by methods of differential thermal analysis.
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Melting / freezing pt.:
- 191 °C
- Atm. press.:
- ca. 1 atm
- Executive summary:
The melting point using DSC was measured according to ASTM E 537.
Reference
The DSC diagram shows two endothermic peaks. The first peak at about 170°C has an endothermic energy of about 8 J/g. Begause of this small energy this peak can ruled out as the the melting point. The second peak has an endothermic energy of about 72 J/g. This is in the range of melting energies. Individual results:
| No. | Sample mass (mg) | Melting Point (°C) |
| 1 | 12.0 | 191.0 |
| 2 | 11.1 | 191.4 |
| 3 | 12.8 | 191.2 |
| Mean | 191.2 |
Description of key information
The melting point of Solvent Violet 59 was approx. 191 °C and no pressure was reported.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 191 °C
