Description of key information

2,4-dichloronitrobenzene as the main constituent of the substance  does not show explosive properties as tested according to the UN test series 1 and 2.
For 2,6-dichloronitrobenzene data not yet available, but 2,6-dichlornitrobenzene as homologous substance is also considered as non-explosive substance.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Differential Thermal Analysis

Onset of exotherm reaction of 2, 4 -dichloronitrobenzene: 320°C

Heat release: 1650 J/g

Trauzl Test (UN F.3)

2, 4 -dichloronitrobenzene exhibits some explosive power and further tests have to be performed.

Propagation of detonation (UN A.1, BAM 50/60 steel tube test)

2, 4 -dichloronitrobenzene is not able to propagate a detonation. From these findings it can be concluded that 2,4-dichloronitrobenzene is not sensitive to detonative shock (UN 2(a)).

Koenen Test (UN 2(b))

2, 4 -dichloronitrobenzene shows no violent effect on heating under confinement.

Time-pressure-test (UN 1(c), UN 2 (c))

2, 4 -dichloronitrobenzene shows no likelihood of deflagration.

Justification for classification or non-classification

2,4 –dichloronitrobenzene as the main constituent of the substance has no potential for explosivity; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008).

For second main constituent of the substance data not yet available, but 2,6-dichloronitrobenzene as homologous substance is also considered as non-explosive substance.
