Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Non-explosive
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
According to the REACH Regulation (EC n. 1907/2006) Annex VII, Column 2 which says, "The study does not need to be conducted if:
- the organic substance or a homogenous mixture of organic substances contains chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 °C."
Though the test substance has two nitro groups on two different aromatic rings in a big molecule (MW 889.59 g/mol), from Differential Scanning Calorimetry its decomposition energy was determined to be 444.0 J/g, and its decomposition range is 262 - 404 °C which satisfies the above criteria.
Therefore, the substance is exempt from testing for explosiveness.
Justification for classification or non-classification
Explosiveness can be defined as the tendency of a substance to undergo violent and rapid decomposition, under appropriate conditions, to produce heat and or gas. Knowledge of explosive properties is an important safety consideration. If explosive substances are handled incorrectly then there can be serious consequences.
According to the REACH Regulation (EC n. 1907/2006) Annex VII, Column 2 which says, "The study does not need to be conducted if:
- the organic substance or a homogenous mixture of organic substances contains chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 °C."

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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
