Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes
- Remarks:
- g-013
- Type of method:
- capillary method
- Melting / freezing pt.:
- >= 250 °C
- Decomposition:
- yes
- Decomp. temp.:
- >= 250 °C
- Conclusions:
- Gradual (visually observed) partially melting decomposition of test item starts from temperature of 250°C.
- Executive summary:
The melting point of the test substance was determined in a GLP study (2009) according to EU method A.1 by using the capillary method with metal block. It has been (visually) observed that gradual partially decomposition starts with the melting process at 250 °C.
Reference
The value of Chelat Fe(III)HBED melting point was visually determined. During the measurement the test item sample was not transparent to light and it was not possible to obtain the results as transmission diagrams. During the temperature rise the brick-red colour of the test item started to brighten gradually at about 250°C.
The visual observations proved that it is not possible to obtain a repeatability of the melting point determination or its decomposition temperature. It was observed on the basis of colour change, gas bubbles formation, turbidity and carbonisation. Maybe the products of decomposition are CO, CO2 and nitrogen oxides.
Description of key information
The melting point of the test substance was determined in a GLP study (2009) by using
the capillary method with metal block. It has been (visually) observed that gradual partially decomposition starts with the melting process at 250 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 250 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
