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:
- 06 January 2017-16 March 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised. Therefore full validation applies.
- 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
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- date of inspection 05 Juillet 2016 / date of issue 28 October 2016
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 65.4 °C
- Decomposition:
- no
- Conclusions:
- The melting point of the test item has been determined to be approximately 65.4 ± 2 °C (338 ± 2 K).
- Executive summary:
The melting point of the test item was measured under GLP according to OECD 102 / EU A1/ OPPTS 830.7200 guideline, by Differential Scanning Calorimetry (DSC).
Aliquots of test item were placed in manually pierced crucibles and were subjected to a thermal program from -10 to 100 °C at 1 °C/min.
The determination was performed in duplicate and the results were within accuracy limits of the method. Therefore the mean value was retained as the result of the study.
No weight change and no indication of decomposition were observed during the tests.

Discussion
The selection of the temperatures range for the determination of the melting point (-10 -100°C), were based upon profiles obtained during boiling point analysis.
Description of key information
The melting point of the test item has been determined to be approximately 65.4 ± 2 °C (338 ± 2 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 65.4 °C
Additional information
A fully reliable GLP experimental study, conducted according to a recognized OECD/EC/OPPTS guidelines, by Differential Scanning Calorimetry (DSC) method, is available. It is considered as a key study. The result is retained as key data.
