Results

An examination of the structure of test material reveals that there are no chemical groups present that would imply explosive properties. The substance does not contain oxygen; therefore an oxygen balance calculation is not possible or required.

Conclusions:

A review of the structure of the test material suggests that there are no chemical groups present that would imply explosive properties and no further testing is required.

Executive summary:

A structural examination was performed for the test material, in order to assess the requirement for further testing of the explosive potential of the compound, in accordance with the ‘Guidance on Information Requirements and Chemical Safety Assessment – Chapter R.7a: Endpoint Specific Guidance’.

A review of the structure of the test material suggests that there are no chemical groups present that would imply explosive properties and no further testing is required.

Description of key information

An expert report (Carling & Liney, 2012) based on a structural evaluation of the test material has been provided as the key study. The report concludes that the test material does not contain explosive properties and thus further testing is not required.

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

A structural examination was performed for the test material, in order to assess the requirement for further testing of the explosive potential of the compound, in accordance with the ‘Guidance on Information Requirements and Chemical Safety Assessment – Chapter R.7a: Endpoint Specific Guidance’.

A review of the structure of the test material suggests that there are no chemical groups present that would imply explosive properties and no further testing is required.

Justification for classification or non-classification

The structural evaluation indicates that the test material is not explosive and therefore does not require classification under Regulation (EC) No. 1272/2008.
