Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 2008-07-17 to 2008-12-18
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
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.
equivalent or similar to guideline
OECD Guideline 102 (Melting point / Melting Range)
closed crucible; single run
GLP compliance:
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

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.
