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:
- Between 12 February and 30 March 2012.
- 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:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Batch# 9311205/008, expiry date 11.2.2013
- Melting / freezing pt.:
- 373 K
- Atm. press.:
- 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- >= 168 - <= 441 °C
- Sublimation:
- no
- Conclusions:
- The melting temperature has been determined to be 100 ± 1 °C (373 ± 1 K). Furthermore, decomposition was observed, starting at 168 °C.
- Executive summary:
The determination of the melting point was carried out by differential scanning calorimetry (DSC) 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. Conclusion: The melting temperature has been determined to be 100 ± 1 °C (373 ± 1 K).
