Executive summary:

An assessment of the oxidising property of the test substance 3,3-(4,4-biphenylenedioxy)dianiline was made on a theoretical consideration of its structure.

It is possible to predict the oxidising potential of a molecule by analogy with existing compounds and therefore it is possible to examine the chemical structure of a substance and ascertain whether or not there are any groups present that are associated with oxidising properties. For this purpose a screening procedure has been published in Appendix 6 of the United Nations ‘Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria’.

For organic compounds, the substance does not possess oxidising properties if it does not contain oxygen, fluorine or chlorine. If these atoms are present, then the substance does not possess oxidising properties if the atoms are chemically bonded only to carbon and hydrogen.

From an examination of the chemical structure of 3,3-(4,4-biphenylenedioxy)dianiline, it was confirmed that it only contained oxygen chemically bonded to carbon. Consequently, the test substance would not be expected to possess oxidising properties.
