- experimental study
- Adequacy of study:
- key study
- Study period:
- Experimental Starting Date: 25 April 2014 Experimental Completion Date: 03 June 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to 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:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- thermal analysis
- Remarks:
- Differential scanning calorimetry (DSC)
- Melting / freezing pt.:
- 464 K
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The melting/freezing temperature of the test item has been determined to be 190.8 ± 0.5 °C (464.0 ± 0.5 K).
- Executive summary:
The determination was carried out by differential scanning calorimetry, using a procedure 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.
Instrument : Mettler Toledo DSC822e Differential Scanning Calorimeter (DSC) incorporating ThermoHaake Cooler EK45/MT.
Sample crucibles : Aluminum crucible with lid.
Reference crucible : Empty aluminum crucible with lid.
Test conditions : The test was performed in an air atmosphere.
Conclusion
The melting/freezing temperature of the test item has been determined to be 190.8 ± 0.5 °C (464.0 ± 0.5 K).

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
