Description of key information

No additional testing is required for explosive properties, based on chemical structure and low decomposition energy.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

According to the screening procedure described in CLP, one structural alert (1,2-diene) was identified in the chemical structure of the substance, therefore the Oxygen Balance was calculated. The result of OB=-286 is sufficient for purpose.

Moreover, a DTA analysis was available as reliable supporting study, with a maximum decomposition energy observed of 306 J/g at 280°C.

Justification for classification or non-classification

Explosive properties

The substance meets the exemption criteria (OB <-200, exothermal decomposition <500 J/g). The acceptance procedure does not apply.

Self-reactive properties

The decomposition energy slightly exceed the exemption criteria (<300 J/g). Further testing should be performed. However, considering the result is borderline to the threshold, no major hazard is anticipated.
