Description of key information

Submission substance is not explosive

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The appraisal of the composition and molecular structure indicate without doubt that the submission substance will not show a rapid decomposition or reaction under release of energy and gaseous reaction products. This theoretical result is supported by the physical properties and the negative total decomposition energy determined by DSC-measurements (see RCC project 742397).

Explosive test articles normally show a very high decomposition energy (>2000 kJ/kg).

In conclusion, the submission substance was considered to be not explosive and no experimental determination had to be performed according to the guideline in force.

Justification for classification or non-classification

Based on structural considerations as well as results from differential scanning calorimetry (exothermic decomposition energy < 500 J/g), no classification requirements exist for the submission substance with regard to explosive properties.
