STATEMENT FOR JUSTIFICATION OF OMISSION OF STUDY
Name of substance: Benzene,
ethenyl, ar–bromo derivs
study: A21: Oxidising properties (liquids)
The oxidising properties were predicted based structural
considerations rather than by formal testing using Method A21 of Council
Regulation (EC) No 440/2008.Screening procedures
represent an intelligent testing strategy (ITS) for oxidising
properties. In accordance with the Guidance on information requirements
and chemical safety assessment, if ITS is applied correctly to the
oxidising properties endpoint, only substances for which it is suspected
will give a positive result in one of the oxidising properties tests
need to be tested.
The structure of the substance was assessed
for chemical groups that would imply oxidising properties. Common
examples of such groups are nitrates, nitrites, organic nitro compounds,
metal oxides, metal oxometallates, N-halogen compounds, N-haloimides,
difluoroaminos, difluoroaminopolynitroaryls and oxohalogen compounds
(e.g. hypofluorites, perchlorates, bromates and iodites).
A review of the structure suggests that there are no chemical
groups present that would imply oxidising properties.
Based on the known chemical and physical properties of the
substance and its chemical structure, a negative result is predicted for
the A21 Oxidising Properties liquids test of Council
Regulation (EC) No 440/2008.As such it is
considered justified to omit the test.
