Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- 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
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
