Description of key information

This substance is not explosive when exposed to thermal or mechanical stress under the conditions of the test.

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

This non explosive nature of this substance was determined by running a test in accordance with EC Directive 84/449 A.14 "Explosive properties" (1984).

In addition, since the molecule contains a nitro group that is known to promote, in some cases, the explosive properties of a molecule, we calculated the Oxygen Balance (OB) of our molecule, according to the guidance document issued by ECHA and found:

OB = -223

Normally, since this value is less than -200, we would not have needed to run a test, however, since we are close to the limit and because of the presence of an azo group in the molecule, we decided to run the experimental test, in accordance with the recommendation of the guidance document. The test confirmed that this substance is not an explosive.
