Administrative data

explosive properties of explosives
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties
Reason / purpose:
data waiving: supporting information
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
18 to 25 Sep 2018
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose:
reference to other study
according to
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
27th July 1995
GLP compliance:
Type of method:
differential scanning calorimetry
Decomp. temp.:
>= 184 °C
Remarks on result:
not determinable

The test item shows no melting of the main component up to 184 °C, according to the definition in the OECD Guideline 102 (mean value from repeat determination).


185 °C (from first measurement)

184 °C (from second measurement)

184 °C (from third measurement)


From 184 °C the test item shows an endothermic effect (decomposition presumably - a melting > 184 °C can't be excluded).


The possible decomposition temperatures according to

- the melting results (184 °C)

- the boiling results (192 °C - see section 4.3)

differ due to different measuring conditions (melting - capsulated crucible / boiling- partially capsulated).


The cooling runs do not show a crystallization of the main component.


At approximately 49 °C the test item shows an endothermic effect. This effect is possibly melting of a part component and / or a solid-solid phase transformation.

In the temperature range between about 82 °C and 94 °C the test item shows a further endothermic effect. This effect is possibly melting of a part component, evaporating of a part component and / or a solid to solid phase transformation.

These effects do not correlate with the melting of the test item (main component) which was verified by subsequent tests with the Kofler-heating bank.
