EC number: 943-080-0 | CAS number: -
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
- Study period:
- From 24 Nov 2015 to 08 Dec 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Melting / freezing pt.:
- > 42.9 - < 45.2 °C
- Atm. press.:
- ca. 1 atm
- Remarks on result:
- other: Melting range. These values are the means from two independent determinations.
- Conclusions:
- The means between both determinations give the following values for the melting range:
Melting range: 42.9 to 45.2 °C (316.1 to 318.4 K) - Executive summary:
The determination of the melting point was performed in duplicate. In both determinations, a melting range was detected.The melting range was determined as 42.9 to 45.2 °C (316.1 to 318.4 K)
These values are the means from two independent determinations.

The means between both determinations give the following values for the melting range:
Melting range: 42.9 to 45.2 °C (316.1 to 318.4 K)
Standard deviation: 0.1 (begin); 0.1 (end)
Estimated accuracy: ± 0.2 °C
Description of key information
In a GLP study according to OECD TG 102, The melting range was determined as 42.9 to 45.2 °C (316.1 to 318.4 K)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 44 °C
Additional information
In a GLP study according to OECD TG 102, The melting range was determined as 42.9 to 45.2 °C (316.1 to 318.4 K).
These values are the means from two independent determinations.
Key value indicated is the mean value between the two range limits.
