Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- other: Expert statement
- Adequacy of study:
- key study
- Study period:
- Study completion date: 13 July, 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Principles of method if other than guideline:
- The screening procedure as described in:
- CLP, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3
- Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria
- Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3 - GLP compliance:
- no
- Parameter:
- other: More sensitive to shock than m-dinitrobenzene
- Remarks:
- migrated information
- Remarks on result:
- not measured/tested
- Parameter:
- other: More sensitive to friction than m-dinitrobenzene
- Remarks:
- migrated information
- Remarks on result:
- not measured/tested
- Parameter:
- other: Explosive under influence of flame
- Remarks:
- migrated information
- Remarks on result:
- not measured/tested
- Parameter:
- other: Explosive (not specified)
- Remarks:
- migrated information
- Remarks on result:
- negative (not further specified)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- 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.
- Executive summary:
In summary, analysis of the chemical structure reveals two nitro-groups present in the molecule representing alert structures for explosive properties. The calculated chemical oxygen balance is above the trigger value of - 200 and the determination of the exothermic decomposition energy demonstrated an energy release above the critical value of 500 J/g while the onset of energy release is below 500 °C. Additional data generated for a product containing about 31.7 % of the crude dye revealed no risk for spontaneous deflagration. A test on dust explosibility was rated positive. Substance decomposition resulted in production of 15 liter gas/ kg test substance including production of flammable gases. The minimum ignition temperature was determined to 390 °C. Based on these results, 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.
Reference
Screening evaluation:
Analysis of the above depicted molecular structure revealed, that no such chemical alert structures are present in the molecule.
Calculation of the oxygen balance according to the above mentioned formula is -159.850 and therefore higher than the trigger value of -200.
Determination of the exothermic decomposition energy:
The curve displays one exothermic peak up to 350 °C with a total energy release of 652.33 J/g. As a result, the overall energy release is above a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
The substance is considered to be non-explosive according to Regulation (EC) 1272/2008, hence no classification is necessary for this criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
