Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

non explosive

Additional information

The exothermic decomposition energy was determined by DSC in a closed, high pressure cell with a heating rate of 2.5 K/min.

The exothermic decomposition energy was found below 500 J/g.

Justification for classification or non-classification

Self-classification according to Regulation (EC) No 1272/2008 on CLP:

Step 1:  Reactive groups: The substance contains one chemical group “Azo”  which might be associated with explosive properties.

Step 2:  Calorimetric test:  The exothermic decomposition energy was found a value of 290 J/g which indicated that the substance does not have a potential for rapid energy release (see section 4.19). Thus, it is not to be classified as an explosive material.
