Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From May 10, 2016 to May 31, 2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
not specified
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Batch no.: 3837
Appearance: white powder
Key result
Decomposition:
yes
Remarks:
probably a thermal decomposition
Decomp. temp.:
225 °C
Remarks on result:
other: atm. press.: not specified

Individual values:

225°C (from first measurement)

225°C (from second measurement)

224°C (from third measurement)

From 225°C the test substance showed most probably a thermal decomposition (a melting >225°C can't be excluded).

Conclusions:
Under the study conditions, the substance did not show any melting and underwent thermal decomposition from 225°C.
Executive summary:

A study was conducted to determine the melting point of the substance according to OECD Guideline 102. To determine the melting behaviour (three independent single measurements), the test substance was measured by DSC between -90°C and 500°C with a heating / cooling rate of 10 K/min in 4 cycles. For the measurement a capsulated crucible was used. Under the study conditions, the substance did not show any melting and underwent thermal decomposition from 225°C (Kintrup, 2016).

Description of key information

The melting point was determined according to OECD Guideline 102 (Kintrup, 2016)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
225 °C

Additional information

Under the study conditions, the substance did not show any melting and underwent thermal decomposition from 225°C.
