Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 August 2006 to 8 December 2006
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Study conducted to GLP 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.
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
other: differential scanning calorimetry
Melting / freezing pt.:
> 633 K
Remarks on result:
other: Atmospheric pressure not reported, but assumed to be standard atmospheric room pressure.
Melting / freezing pt.:
> 360 °C
Remarks on result:
other: Atmospheric pressure not reported, but assumed to be standard atmospheric room pressure.

Overall result: melting temperature greater than 360°C (633 K).

Conclusions:
The melting temperature of the test material has been determined to be greater than 633 ± 0.5K.
Executive summary:

In a general physico-chemical properties study (0370/0351), the melting/freezing temperature of the test material was determined to be greater than 633 ± 0.5 K (360 ± 0.5 °C), according to OECD Test Method 102.

Description of key information

The melting temperature of the test material has been determined to be greater than 633 ± 0.5K.

Key value for chemical safety assessment

Additional information

In a general physico-chemical properties study (0370/0351), the melting/freezing temperature of the test material was determined to be greater than 633 ± 0.5 K (360 ± 0.5 °C), according to OECD Test Method 102. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
