Key result
Parameter:
other: Determination of the exothermic decomposition energy
Remarks on result:
other: The overall energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.
Key result
Parameter:
other: Oxygen balance
Remarks on result:
other: The calculated oxygen balance was -128.35 and therefore higher than the trigger value of -200.

Screening evaluation:

Analysis of the molecular structure revealed that one azo group representing a chemical alert structure for explosive properties is present in the molecule.

The calculated oxygen balance was -128.35 and therefore higher than the trigger value of -200.

Determination of the exothermic decomposition energy:

The curve displayed one exothermic peak between 180 °C and 270 °C with a total energy release of 20.46 J/g which was considered to represent substance decomposition. As a result, the overall energy release was below a critical trigger level of 500 J/g and the onset of energy release was below 500 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The substance is considered to be non-explosive based on the screening evaluation.
Executive summary:

A screening for the explosive properties of the test substance was carried out according to internationally accepted guidelines. Analysis of the chemical structure revealed one azo group representing a chemical alert structure for explosive properties present in the molecule. The calculated chemical oxygen balance was above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore the substance was considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 and no further testing is required.

Description of key information

The substance was considered to be non-explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

A screening for the explosive properties of the test substance was carried out according to internationally accepted guidelines. Analysis of the chemical structure revealedone azo group representing a chemical alert structure for explosive properties present in the molecule. The calculated chemical oxygen balance was above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 and no further testing is required.

Justification for classification or non-classification

Based on the result of the screening evaluation for explosive properties, the substance does not warrant classification according to the CLP (Regulation EC No. 1272/2008) criteria.
