Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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.

Description of key information

The substance decomposes >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
