Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- For justification of read-across please refer to the read-across report attached to IUCLID section 13.
- Reason / purpose for cross-reference:
- read-across source
- Key result
- Melting / freezing pt.:
- > 90 °C
- Atm. press.:
- ca. 1 010 mBar
- Decomposition:
- yes
- Decomp. temp.:
- > 150 °C
- Conclusions:
- The test item started to melt at 90°C followed by decompensition.
- Executive summary:
The melting point / melting range of the test substance was determined via Differential Scanning Calorimetry (DSC) and capillary tube in a metal block according to OECD 102.
For DSC, 12.61 mg and 10.03 mg of the test substance were heated constantly until the final temperature (450°C) is reached, while measuring the quantity of heat absorbed or released. The substance melted from 90°C to 150°C and was observed to be black after measurement.
For the capillary tube method, the test item was filled to a height of approx. 5 mm into the test tube and heated to the maximum temperature (410°C), while any changes of the substance are observed and recorded. The substance started to melt from 104°C. At 123°C the substance was completely melted and turned black.
According to these results, the substance starts to melt at 90°C followed by decomposition.
This information is used in a read-across approach in the assessment of the target substance.
For justification of read-across please refer to the attached read-across report (see IUCLID section 13).

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
