Description of key information

The substance is considered to be non-explosive.

Key value for chemical safety assessment

non explosive

Additional information

The explosiveness of the registered substance was estimated via an assessment based on an examination of the molecular structure and composition of the substance and relevant experimental data. An analysis of the substance has been performed to identify the presence of any structural features commonly associated with explosive behaviour. The conclusions are summarised in the table below.

Functional Group


C-C unsaturation (acetylenes, acetylides, 1,2-dienes)

The only unsaturation present is the aromatic ring however this is a relatively unreactive moiety and does not bear additional functionality known to be associated with explosive behaviour.

C-Metal and N-Metal (Grignard reagents, organo-lithium compounds)

Not present

Contiguous N atoms (azides, aliphatic azo compounds, diazonium salts, hydrazines

Not present

Contiguous O atoms (peroxides, ozonides)

Not present

N-O (hydroxylamines, nitrates, nitro compounds, nitroso compounds, N-oxides)

Not present

N-Halogen (chloramines, fluoroamines)

Not present

O-Halogen (chlorates, perchlorates)

Not present

In addition to the structural assessment, the substance has been analysed by differential scanning calorimetry and thermogravimetric analysis up to 500°C. There is no evidence of significant exothermic events with associated mass losses that would indicate potential explosive behaviour. In conclusion, the substance is not an explosive.

Justification for classification or non-classification

The substance is considered to be not classified as an explosive as there are no structural features of the substance associated with explosiveness. In addition, there was no evidence of significant exothermic events with associated mass losses during thermal analysis for melting point determination (see section 4.8).
