Key result
Decomposition:
ambiguous
Remarks:
At 365°C, the colour of the test substance changed to silver.
Decomp. temp.:
>= 365 °C
Remarks on result:
not determinable
Remarks:
In the preliminary test up to 400 °C no melting point as described in the guideline could be observed. At 365 °C the colour changed to silver.
Conclusions:
For Reactive Red 24, no melting point according to the criteria described in the guideline could be observed up to 400 °C.
Executive summary:

The determination of the melting point was performed by visual judgement using the capillary method.

In the preliminary test up to 400 °C no melting point as described in the guideline could be observed. At 365 °C the colour changed to silver.

In conclusion, for Reactive Red 24 no melting point according to the criteria described in the guideline could be observed up to 400 °C.

Description of key information
