Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Test substance thermally stable:
Key result
Operating temp.:
>= 250.67 °C
Remarks on result:
not determinable
Transformation products:
not measured
A screening test via DSC (differential scanning calorimetry) was conducted from
0°C to 520 °C.
During the DSC run an exothermal event (which could be caused by decomposition based
on the observations which were made after opening the crucible) was observed with an
onset of 250.67 °C and this was integrated to derive the related energy (in J/g). The related energy of the observed exothermal event was 559.22 J/g.
Based on the exothermal event, it is stated:
- As the released energy is more than 300 J/g, the test item is subject to the classification procedures for self-reactive substances.
- And as the released energy is more than 500 J/g, the acceptance procedures for
Class 1 explosives need to be applied.
according to the “UN Recommendations on the Transport of Dangerous Goods; Manual of
Tests and Criteria”; sixth revised edition, 2015, Section 20.2.1, and Appendix 6,
section 3.3.c.
The measurement of indium after calibration met the validity criteria. Therefore, the result
of the study is considered valid.

Description of key information

According to OECD 113

Additional information

Justification for classification or non-classification

No self-ignition was observed up to the melting point. No exothermic effect on the test substance found below 180ºC. Thus the test substance is considered stable at room temperature based on the criteria as outlined in the OECD Guidelines. The exothermal event was recorded at 250.67ºC.
