Screening evaluation

Analysis of the molecular structure revealed that one nitro group representing an alert structure for explosive properties is present in the molecule.

Calculation of the oxygen balance according to the above mentioned formula is -170.06 and therefore higher than the trigger value of -200.

Determination of the exothermic decomposition energy

The curve displays one exothermic peak between 310 and 350 °C with an overall energy release of 72.03 J/g which is regarded to be due to substance decomposition. As a result, the overall energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Interpretation of results:
other: No explosive properties
Conclusions:
FAT 92504/C is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008.
Executive summary:

No experimental test data according to EU Method A.14 or comparable methods for Disperse Blue 054/077 are available. Analysis of the molecular structure revealed that one nitro group representing an alert structure for explosive properties is present in the molecule. The calculated chemical oxygen balance is 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) 1272/2008 and no further testing is required.

Description of key information

FAT 92504/C is considered to be non-explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

No experimental test data according to EU Method A.14 or comparable methods for Disperse Blue 054/077 are available. Analysis of the molecular structure revealed that one nitro-group representing an alert structure for explosive properties is present in the molecule. The calculated chemical oxygen balance is 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) 1272/2008 and no further testing is required.

Justification for classification or non-classification

FAT 92504/C is considered to be not explosive, hence no classification is required according to the Regulation (EC) No. 1272/2008.
