Study period:
16/06/2015 - 12/10/2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
A GLP study
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:

Appearance: Beige Powder
Key result
Decomposition:
ambiguous
Decomp. temp.:
>= 96 - <= 146 °C

The mean of at least three measurements, which are in the range of the estimated accuracy, is reported as the melting temperature.

Conclusions:
Suspected sample decomposition was observed during four test runs between 96 oC and 145 oC. The sample was observed to expand and rise up the sample tube.
Executive summary:

The melting point of the test item was measured according to EC method A.1. Suspected sample decomposition was observed during four test runs between 96 oC and 145 oC.

Description of key information

Suspected sample decomposition was observed during four test runs between 96 oC and 145 oC.

Key value for chemical safety assessment
