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
- Study period:
- 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Principles of method if other than guideline:
- The melting point of the substance as a pale brown solid (isolated with care and difficulty under high vacuum) was measured using a Stuart Scientific SM3 electrothermal melting point apparatus with a 1 °C/min temperature ramp rate.
- GLP compliance:
- not specified
- Type of method:
- thermal analysis
- Specific details on test material used for the study:
- batch # 110200/51
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 175 °C
- Conclusions:
- It was found that the substance did not melt but decomposed to a deeply brown/black solid >175 °C.
- Executive summary:
The melting point of the substance as a pale brown solid was measured using a Stuart Scientific SM3 electrothermal melting point apparatus with a 1 °C/min temperature ramp rate and it was found that the substance did not melt but decomposed to a deeply brown/black solid >175 °C.

The liquid solution will freeze < 0 C. The melting/freezing point of 0 C isused for the CSA
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 0 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
