- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Experimental dates: 21-22 November 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognized method, and under GLP. No deviation was reported. The test substance is adequately characterised. Therefore full validation applies.

- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- Regulation (EC) No. 440/2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspection 20-21 June 2017, signed on 04 September 2017
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Storage conditions: Ambient temperature (10 °C to 30 °C) in original glass bottle.
The sample was tested as received. No further preliminary treatment such as drying or milling was performed. - Key result
- Melting / freezing pt.:
- 117.6 °C
- Atm. press.:
- 1 013.3 hPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 280 °C
- Executive summary:
The melting point of the test substance was determined under GLP according to OECD 102 / EU A1 guidelines, using Differential Scanning Calorimetry method.
The determination was carried out in aluminium pierced crucible, with a heating rate of 10 K/min, under nitrogen flow. Duplicate results were consistent, so the average value was retained.
The mean melting point was measured at 117.6°C.
Further heating led to decomposition, starting from 280°C.
Reference
The measurements showed an endothermal effect (melting) in the temperature range of 110 – 130 °C. The onset temperature was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline.

Test item was a solidified melt |
Duplicate measurements were within accuracy (±0.5 °C), therefore a mean value was calculated.
The test item had a mean melting point of 117.6 °C.
No endothermal effect was observed after melting occurred; decomposition took place starting at approximately 280°C (peak ca 350°C).
Description of key information
The melting point (transition from solid to liquid) was measured at 117.6°C, followed by decomposition starting from ca 280°C (under nitrogen).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 117.6 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study, and the result is retained as key data.
