However since such high temperatures are not found under normal circumstances of transportation and use, thus Tetrasodium 2,2'-[1,4-phenylenebis[carbonylimino [2-acetamido-4,1-phenylene]azo]]bis[5-[(4-sulphonatophenyl)azo] benzenesulphonate] was considered non-flammable for chemical safety assessment.
Explosiveness:
The study does not need to be conducted because the substance contains chemical groups associated with explosive properties which include oxygen, but the calculated oxygen balance is less than -200 i.e obtained value is -127.
Oxidising properties:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
