Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

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:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Principles of method if other than guideline:
- Method: measured with differential scanning calorimeter DSC-7 of Perkin-Elmer
Discrepancy between documented test parameters and standard methods, but scientifically acceptable - GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- >= 155.8 - <= 157.4 °C
- Executive summary:
In a study similar to OECD Guideline 102 the melting point of the test item was determined by differential scanning calorimetry to be >= 155.8 and <=157.4 °C.
Reference
Description of key information
Based on the most reliable information, the melting point of the test item is considered to be 155.8 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 155.8 °C
Additional information
Key information
In a study similar to OECD Guideline 102 the melting point of the test item was measured by differential scanning calorimetry to be >= 155.8 and <=157.4 °C (BASF AG, 1990).
Supporting information
The melting point of the test item was determined to be 156.5 °C (SRC PhysProp, 2008).
Conclusion
Based on the most reliable information, the melting point of the test item is considered to be 155.8 °C. This result corresponds to the value 156.5 °C provided in the literature (SCR PhysProp, 2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
