Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Diss Factsheets

Administrative data

Endpoint:
boiling point
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid which melts above 300°C
Justification for type of information:
no indication of melting below 300°C
Cross-reference
Reason / purpose for cross-reference:
data waiving: supporting information
Reference
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

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.

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.
