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:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Justification for type of information:
- Using recognised methods described incompany report. This also corrolates with published data suggesting no melting point < 300 C
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Principles of method if other than guideline:
- Melting point estimate was carried out using a Maplelab Scientific Melting Point Device MPD02 up to 300 C
- GLP compliance:
- no
- Type of method:
- capillary method
- Specific details on test material used for the study:
- Batch number of test material: C-04-3584
- Key result
- Melting / freezing pt.:
- > 100 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Remarks:
- Above 100 C
- Decomp. temp.:
- > 100
- Sublimation:
- no
- Conclusions:
- Results: Substance does not melt .The substance decomposes >300 °C.
During normal use and handling, and certainly under biological and environmental conditions, the substance will remain solid.
Reference
Substance does not melt .The substance decomposes > 100 C.
The MPD02 equipment could only go up to 300 C and at this temperature no physical or colouration changes were observed in the crystalline sample placed in the glass capillary tube.
A 1 g sample was heated in a carbolite furnace to 900 C after which it has changed to a dark ash, therefore decomposition had occurred.
Description of key information
Results: Substance does not melt . The substance decomposes >100 °C.
During normal use and handling, and certainly under biological and environmental conditions, the substance will remain solid.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 300 °C
