Administrative data

Endpoint:
relative self-ignition temperature (solids)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid having a melting point <= 160°C
Cross-reference
Reason / purpose:
data waiving: supporting information
Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Reference:
Composition 0
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
not specified
Qualifier:
equivalent or similar to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
not specified
GLP compliance:
no
Type of method:
differential scanning calorimetry
Test material information:
Composition 1
Melting / freezing pt.:
129.21 °C
Atm. press.:
101.3 kPa
Decomposition:
yes
Decomp. temp.:
>= 222.19 - <= 316.16 °C
Sublimation:
no
Remarks on result:
other: Atmospheric pressure assumed

The sample was observed to undergo an endothermic event with the peak at 129.21°C. This was followed by an exothermic peak at 251.06°C.

Conclusions:
The melting point of the substance was determined to be 129.21°C using differential scanning calorimetry (DSC).
