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:
- Testing was conducted between 15 June 2011 and 20 December 2011.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- thermal analysis
- Remarks:
- differential scanning calorimetry (DSC)
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 119 °C
- Sublimation:
- no
- Remarks on result:
- not determinable
- Remarks:
- The test item has been determined to decompose from approximately 119°C (392 K) without melting.
- Conclusions:
- Visual assessment of the melting temperature, determined using a metal blcok apparatus, indicated that the test item has been determined to decompose from approximately 119°C (392 K) without melting.
- Executive summary:
The determination was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86 and a procedure using a capillary in a metal block device, designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
The test item has been determined to decompose from approximately 119°C (392 K) without melting.

Results
Thermograms for Determinations 1 and 2 are shown in Figure 5.1 and Figure 5.2 (see attachment 1 in attached background material).
Visual determination
The test item was observed to change in colour from a cream powder to a grey solid from approximately 119°C (392 K), indicative of decomposition.
Description of key information
The test item has been determined to decompose from approximately 119°C (392 K) without melting.
Key value for chemical safety assessment
Additional information
As a result of the low rate of enthalpy change during decomposition, the temperature at which the onset of decomposition occurred could not be determined by differential scanning calorimetry (DSC).
A visual assessment of the melting temperature was determined using a metal block apparatus. A small amount of test item was ground and placed in a capillary tube fused at one end. The test item was observed to change in colour from a cream powder to a grey solid from approximately 119°C (392 K) indicative of decomposition.
