Pressure was not reported. It is assumed that melting point was tested at ambient conditions.
Pressure was not reported. It is assumed that melting point was tested at ambient conditions.
Pressure was not reported. It is assumed that melting point was tested at ambient conditions.
Lower measured melting point: 46.0 °C
Higher measured melting point: 58.0 °C
The pressure was not reported in the certificate of analysis; melting point measured according to open capillary method, therefore ambient conditions can be assumed (pressure ca. 1013 hPa).
Description of key information
Melting point = 54.3 °C (Eur. Ph. 2.2.15, Open Capillary Method)
Pressure not reported, assumed to be normal pressure (1013 hPa).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 54.3 °C
Additional information
Melting point values from three reliable sources have been chosen as supporting information:
54 °C (Handbook of Chemistry and Physics – 86th Edition 2005-2006, 2005)
54 °C (The Merck Index - An Encyclopedia of Chemicals and drugs - Ninth Edition, 1976)
52-56 °C (Souto et al., J Microencapsul, 2005)
