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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Melting / freezing pt.:
- 227.4 °C
- Remarks on result:
- other: atmospheric pressure
- Conclusions:
- The melting point was determined as 227.4 °C at atmospheric pressure.
- Executive summary:
The test was conducted according to EC test Procedure A.1 'Melting/Freezing Temperature' and ASTM E 537 'Standard method for assessing the thermal stability of chemicals by methods of differential thermal analysis'.
The measurement was done by Differential Scanning Calorimetry. Macrolex Orange R and reference crucible with an inert sample were subjected to the same controlled temperature program. The sample was heated in a glass crucible at a linear rate of 1 K/min from 210 °C up to 240 °C. The measurement was recorded electronically.
The melting point was determined as 227.4 °C at atmospheric pressure.

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.
