Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 2008-07-17 to 2008-12-18
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Remarks:
The study was conducted similarly to guideline, with acceptable deviation. The substance is considered to be adequately characterised with its purity. Therefore validation applies, with restrictions.
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
yes
Remarks:
closed crucible; single run
GLP compliance:
no
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Storage condition of test material: in a refrigerator at about 4°C.
Key result
Melting / freezing pt.:
ca. 80 °C
Decomposition:
no

The DSC trace provided in the report shows a sharp endotherm peak, starting from about 70°C, with a maximum at about 85°C, and ending at about 90°C. The extrapolated onset temperature is expected to be ca 80°C.

Executive summary:

The test substance was investigated for explosive properties, including Differential Scanning Calorimetry screening test. Experimental conditions are acceptable for purpose.

The DSC trace shows a sharp endotherm, that can be interpreted as the melting temperature of the sample.

The melting point of the test substance is ca 80°C.

Description of key information

Sharp melting transition expected at ca 80°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
80 °C

Additional information

A reliable study, conducted according to a recognized OECD/EU method is available. Despite restrictions due to test conditions, it is considered as a key study. The result is retained as key data for purpose of CSA.
