Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
13 June 2006 to 05 July 2006
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
334 K
Remarks on result:
other: The determination was conducted in air (static)

The resulting thermograms indicated thermal events (endotherms) at 60.97 °C (determination 1) and 60.43 °C (determination 2).

The mean melting temperature of the test material was therefore determined to be 60.7 °C (equivalent to 334 K).

Conclusions:
Under the conditions of the study the melting temperature of the test material was determined to be 60.7 °C (equivalent to 334 K).
Executive summary:

The melting temperature of the test material was investigated in a study which was conducted in accordance with the standardised guideline EU Method A.1, under GLP conditions using differential scanning calorimetry.

Under the conditions of the study the melting temperature of the test material was determined to be 60.7 °C (equivalent to 334 K).
